     FIELD OF THE INVENTION 
     The invention relates to methods for preparing pyrrolotriazine pharmaceutical compounds having activity as kinase inhibitors and, in particular, to methods for making pyrrolotriazine-containing compounds useful for treating kinase-associated conditions. The invention also includes an efficient method of aminating pyrrole compounds useful in the synthesis of pyrrolotriazines and other N-aminated heterocyclic compounds. 
     BACKGROUND OF THE INVENTION 
     The invention generally relates to methods for preparing compounds useful as kinase inhibitors or alternatively, as components or precursors in the synthesis of kinase inhibitors. 
     Pyrrolotriazine compounds useful as kinase inhibitors are disclosed in U.S. patent application Ser. No. 09/573,829 filed May 18, 2000, which is commonly assigned with this application. Pyrrolotriazine compounds substituted with an acidic group reportedly having sPLA 2 -inhibitory activity are disclosed in WO 01/14378 A1 to Shionogi &amp; Co., Ltd, published Mar. 1, 2001 in Japanese. The entire disclosure of each of the patent applications, patents, and publications referred to herein is incorporated herein by reference.

     In particular, the invention provides an improved method of preparing such compounds when compared to other methods involving animation of a readily available pyrrole starting reactant. The reaction using chloramine provides an aminated pyrrole in acceptable yields while avoiding the use of more hazardous aminating reagents. In contrast to the use of chloramine, for example, it has been found that aminating agents such as dinitro-substituted phenylhydroxylamines have been determined to be explosive, and to produce dinitrophenols, which are known toxic by-products (MSDS). Other aminating reagents such as hydroxylamine-O-sulfonic acid (HOSA), gave inferior yields (10–12%). Amination of pyrroles using oxaziridines also gave inferior results. Attempts at nitration of the desired pyrroles were also unsuccessful. 
     In certain preferred embodiments, the present invention is directed to a method of making pyrrolotriazine compounds of Formula (II):

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION 
     The invention comprises, in one aspect, a method of preparing pyrrolotriazine kinase inhibitors using a suitably substituted pyrrole as a starting material. According to certain preferred embodiments of the method, a pyrrole is reacted with a strong base, then aminated using a reactive haloamine, preferably chloramine. Suitably, this amination step is performed in a protic or aprotic solvent such as ether, MTBE, THF, toluene, water, DMF, NMPO, and DME, however other solvents may also be used. The resulting product can then be cyclized to form a pyrrolotriazine containing intermediate, which may optionally be further reacted to form the kinase inhibitors. It is also recognized that amination of the pyrrole can be used in applications other than cyclization to form pyrrolotriazines. 
     As used herein, the terms “cyclized” or “cyclizing” are intended to encompass any reactions that result in the formation of a 5- or 6-membered ring structure adjunctly connected to the pyrrole ring. 
     Listed below are definitions of various terms used to describe this invention. These definitions apply to the terms as they are used throughout this specification, unless otherwise limited in specific instances, either individually or as part of a larger group. 
     The term “alkyl” refers to straight or branched chain unsubstituted hydrocarbon groups of 1 to 20 carbon atoms, preferably 1 to 7 carbon atoms. The expression “lower alkyl” refers to unsubstituted alkyl groups of 1 to 4 carbon atoms. When a subscript is used with reference to an alkyl or other group, the subscript refers to the number of carbon atoms that the group may contain. The term “C 0-4 alkyl” includes a bond and alkyl groups of 1 to 4 carbon atoms. 
     The term “substituted alkyl” refers to an alkyl group substituted by one to four substituents selected from halo, hydroxy, alkoxy, oxo (═O), alkanoyl, aryloxy, alkanoyloxy, amino, alkylamino, arylamino, aralkylamino, disubstituted amines in which the 2 amino substituents are selected from alkyl, aryl or aralkyl; alkanoylamino, aroylamino, aralkanoylamino, substituted alkanoylamino, substituted arylamino, substituted aralkanoylamino, thiol, alkylthio, arylthio, aralkylthio, alkylthiono, arylthiono, aralkylthiono, alkylsulfonyl, arylsulfonyl, aralkylsulfonyl, sulfonamido, e.g. SO 2 NH 2 , substituted sulfonamido, nitro, cyano, carboxy, carbamyl,. e.g. CONH 2 , substituted carbamyl e.g CONHalkyl, CONHaryl, CONHaralkyl or cases where there are two substituents on the nitrogen selected from alkyl, aryl or aralkyl; alkoxycarbonyl, aryl, substituted aryl, guanidino and substituted or unsubstituted heterocyclos, such as indolyl, imidazolyl, furyl, thienyl, thiazolyl, pyrrolidyl, pyridyl, pyrimidyl and the like. Where the substituent on the alkyl is further substituted, it will be with alkyl, alkoxy, aryl, or aralkyl. 
     When the term alkyl is used in connection with another group, as in heterocycloalkyl or cycloalkylalkyl, this means the identified group is bonded directly through an alkyl group which may be branched or straight chain. In the case of substituents, as in “substituted cycloalkylalkyl,” the alkyl portion of the group may, besides being branched or straight chain, be substituted as recited above for substituted alkyl groups and/or the connected group may be substituted as recited herein for that group. 
     The term “halogen” or “halo” refers to fluorine, chlorine, bromine and iodine. 
     The term “aryl” refers to monocyclic or bicyclic aromatic hydrocarbon groups having 6 to 12 carbon atoms in the ring portion, such as phenyl, naphthyl, biphenyl and diphenyl groups. When the aryl is substituted, each ring of the aryl may be substituted. 
     The term “substituted aryl” refers to an aryl group substituted by one to four substituents selected from alkyl, substituted alkyl, halo, trifluoromethoxy, trifluoromethyl, hydroxy, alkoxy, alkanoyl, alkanoyloxy, amino, alkylamino, aralkylamino, dialkylamino, alkanoylamino, thiol, alkylthio, ureido, nitro, cyano, carboxy, carboxyalkyl, carbamyl, alkoxycarbonyl, alkylthiono, arylthiono, arylsulfonylamine, sulfonic acid, alkysulfonyl, sulfonamido, and aryloxy. The substituent may be further substituted by hydroxy, alkyl, alkoxy, aryl, substituted aryl, substituted alkyl or aralkyl. 
     The term “aralkyl” refers to an aryl group bonded directly through an alkyl group, such as benzyl, wherein the alkyl group may be branched or straight chain. In the case of a “substituted aralkyl,” the alkyl portion of the group may, besides being branched or straight chain, be substituted as recited above for substituted alkyl groups and/or the aryl portion may be substituted as recited for substituted aryl. Thus, the term “optionally substituted benzyl” refers to the group 
                         
wherein each R group may be hydrogen or may also be selected from alkyl, halogen, cyano, nitro, amino, hydroxy, alkoxy, alkylthio, phenyl, benzyl, phenyloxy, and benzyloxy, and other groups recited above.

     A mixture of commercially-available 4-amino-3-methylbenzoic acid (100 g, 0.66 mol) and N-(tert-butoxycarbonyl)anhydride (150 g, 0.68 mol) in THF (1000 mL) was slowly heated to 50° C. overnight. The resulting mixture was cooled to rt and the solvent was removed on a rotary evaporator. The resulting solids were triturated with hexanes and dried in vacuo to afford 151 g (91%) of the crude BOC-protected aniline intermediate as a light pink solid. 
     To the above, light-pink solid was added EDCI (127 g, 0.66 mol), HOBt (90 g, 0.66 mol), and DMF (1000 ml), and the resulting mixture was stirred at rt for 30 minutes followed by addition of methoxyamine hydrochloride (55 g, 0.66 mol) in one portion. After stirring for 10 min, the mixture was cooled using an ice bath. DIPEA (250 ml, 1.4 mol) was added at such a rate so as to maintain the internal reaction temperature below 25° C. After the addition was complete, the ice bath was removed and the reaction was stirred overnight at rt. The reaction mixture was partitioned between 0.5 L of water and 1.5 L of EtOAc and the resulting layers were separated. The aqueous portion was extracted with additional EtOAc (400 mL×3), and the combined organic extracts were washed with water (300 mL×3), cold 0.5 N aq. HCl (400 mL×2), and water (500 mL). The product was then extracted with cold 0.5 N aq. NaOH (300 mL×3) and the combined basic aqueous extracts were neutralized to pH=8 by a slow addition of cold 0.5 N aq. HCl. The resulting solid which precipitated was collected by filtration and washed with cold water. The wet solid was decolorized in hot EtOH with active charcoal to give 106 g of white solid as the BOC-protected N-methoxyamide intermediate. 
     To a slurry of the above solid (91 g, 0.32 mol) in 1,4-dioxane (400 mL) at rt was added a 4M solution of HCl in dioxane (400 mL), and the resulting mixture was stirred at rt overnight. Diethyl ether (1000 mL) was added and the precipitated solid was collected by filtration and triturated with a hot EtOH/H 2 O mixture (4:1 v/v). Drying the resulting solid in vacuo afforded 53 g of the pure hydrochloride salt (Compound D) as a white solid.  1 H NMR (d 6 -DMSO): δ 9.5–9.9 (br. s, 1H), 7.75 (s, 1H), 7.55 (d, 1H), 7.36 (d, 1H), 3.70 (s, 3H), 2.38 (s, 3H). 
     
       
         
         
             
             
         
       
     
     To a solution of the Compound D (41.2 g, 190 mmol) in DMF (230 mL) was added DIPEA (33.1 mL, 180.7 mmol, 0.95 equiv), and the reaction vessel was heated to 55 ° C. (oil bath temp). Solid Compound C (45.6 g, 190 mmol) was added in several portions over 10 minutes and the flask was rinsed with DMF (150 mL) and added to the reaction. The reaction was heated for 10 hours at 55 ° C. and cooled to rt. The mixture was then poured into 1.5 L water diluted to 2.2 L with ice slowly over 10 minutes. The pH was adjusted to 6 and the solids were stirred for 1 h. The solids were filtered, washed with water (2×200 mL) and dried on the filter to give 71.9 g crude ester. The solid was then suspended in acetonitrile (450 mL) and heated with stirring at 50 ° C. for 1 h. The mixture was cooled and filtered to give 64.2 g product (&gt;99% purity). These solids were then dissolved in hot EtOH (2.8 L) and decolorizing carbon (6.4 g) was added followed by heating at reflux for 15 min. The mixture was then filtered through a pad of celite and the reaction flask rinsed with hot EtOH (1 L). The hot filtrate was then concentrated to ˜1 L of EtOH by distillation upon which the product started to crystallize out of solution at a volume of 2.5 L. The solution was cooled and placed in a cold room with stirring for 40 h. The solids were filtered and rinsed with 1/1 EtOH/Et 2 O (500 mL) to give 58.5 g of Compound E as a white solid (80%). 
     F. To a solution of ester Compound E (22.5 g, 58.7 mmol) in THF (205 mL) was added 1 N NaOH (205 mL) and the reaction mixture heated to 50 ° C. for 16 h. The THF was removed in vacuo and the mixture was acidified to pH 4–5 with IN aq. HCl to precipitate the product. The heterogeneous mixture was stirred for 1 h, filtered and washed with water (150 mL) and ether (150 mL). The collected solids were partially dried on the filter to give the crude acid intermediate as a moist white solid which was used without further purification. 
     To a solution of the moist acid in 300 mL of DMF was added HOBt (11.9 g, 88.0 mmol), EDCI (16.9 g, 88.0 mmol) and 1.3 equivalents (117 mmol) of cyclopropyl-amine as the free base or as the hydrochloride salt. The mixture was stirred for 30 min to solubilize the solids, placed in a cold water bath, and DIPEA (20.4 mL, 117 mmol) was added slowly via syringe. The reaction mixture was allowed to stir at rt for 1 h, then poured into rapidly stirred ice water (1.2 L) to precipitate the product. After stirring for 3 h, the solids were collected by suction filtration, washed with water (150 mL) and ether (2×100 mL), and allowed to air dry by suction filtration to give Example 2 (92–98%) as a white solid.

     Example 37 as a free base was charged with acetone (10 ml/g), and the jacket was heated to 50–60° C. Reflux was started at 55–57° C., and the mixture was stirred for 30 min. at 50–60° C. Methanesulfonic acid (1.2 eq.) was added, and a slight exotherm was observed. The slurry was stirred at 50–60° C. until DSC showed in two consecutive samples the complete conversion of the free base (mp 220–222° C.) to the mesylate salt (mp 259–261° C.). The slurry was cooled to 20–25° C. over about 30 min, and then stirred for at least 30 min. with the temp. kept at 20–25° C. The slurry was then filtered, washed with acetone, and dried in vacuo at 40–50° C. to an LOD &lt;0.5% to provide Example 65 as a white crystalline solid (yield 90–95%). [M+H] + =478.4. The above procedure may be used to prepare mesylate salts of other compounds of Formulae (I) and (II) herein.

     To a solution of 4-methyl-3-nitroaniline [compound (1a) from Scheme 8)(3.72 g, 24.5 mmol)] in 150 ml of DCM at rt was added 3-fluorobenzenesulfonyl chloride (5.00 g, 25.7 mmol), followed by TEA (7.0 ml, 50.2 mmol) via syringe. The resulting mixture was stirred for 20 h and the solvent removed in vacuo. The residue was dissolved in DCM (600 ml), washed with sat&#39;d aq. NaHCO 3 , dried over sodium sulfate, filtered, and concentrated in vacuo to give 8.00 g of dark solid which was triturated with DCM to afford 5.46 g of yellow solid. A portion of this solid (1.63 g) was dissolved in 10 ml IN aq. NaOH and 20 ml THF, and the solution was stirred at rt for 20 h. The solvent was removed in vacuo and the residue acidified with 3N HCl to a pH of 2. The resulting precipitated solid was collected by filtration to afford 1.02 g (94%) of a light yellow solid as the desired Compound A.
