Procedure:
To a suspension of 3-(benzyloxy)-6-methyl-4-oxo-4H-pyran-2-carboxylic acid (2.0 g, 7.685 mmol) in H2O (10 ml) in a reaction tube with a stirrer, was added cyclopropylamine (2.13 ml, 30.74 mmol). A clear light yellow solution was formed. The reaction mixture was heated for ca. 19 h in a sealed tube. The reaction mixture then worked up as described in Procedure II. Thus, the title compound (2.14 g, 93%) was obtained as an off white solid.

Procedure:
L-arginine (17.4 g, 0.1 mmols) were dissolved in 100 ml of water in a three-necked round flask, and 100 ml of propanol were added thereto. Dodecyl glycidyl ether [made by Sakamoto Yakuhin Kogyo Co., Ltd., 24.2 g (0.1 mols)] was added thereto dropwise over a period of 30 minutes while being heat-stirred under reflux, and the mixture was stirred as such under reflux, for 3 hours. After it was identified through TLC and gas chromatography that dodecyl glycidyl ether disappeared, the residue was neutralized with 10.1 g (0.1 mols) of 36-% hydrochloric acid. The reaction solution was concentrated under reduced pressure, and the residue was purified through silica gel column chromatography (Kieselgel 60 made by Merck & Co., Inc., eluent--mixture of chloroform, methanol and acetic acid at a ratio of 3:1:0.5) to give 15.0 g of N-(2-hydroxy-3-dodecyloxypropyl)-L-arginine hydrochloride in a yield of 36.0%.

Procedure:
In a slight variation in the method to the 2,4-diamino-5,6-disubstituted-5-deazapteridines described above, using a method taught by A. Pidcock et al (J. Organometallic Chem. 1981, 215, 49-58), 4-bromo-2,3-dihydro-2,2-dimethyl-3-benzofuranone is reacted with hexamethylditin in the presence of tetrakis(triphenylphosphine)palladium(0)in toluene, yielding (2,3-dihydro-2,2-dimethyl-3-benzofuranon-4-yl)tin. The organometallic derivative is then reacted with 2-amino-3-cyano-5-iodo-4-methylpyridine, again in the presence of tetrakis(triphenylphosphine)palladium(0) in toluene, affording the corresponding 2-amino-3-cyano-5-(2,3-dihydro-2,2-dimethyl-3-benzofuranon-4-yl)-4-methylpyridine. This compound is then cyclized with guanidine in ethanol, as previously described, yielding the corresponding 2,4-diamino-5-methyl-6-(2,3-dihydro-2,2-dimethyl-3-benzofuranon-4-yl)-5-deazapteridine. Example 9 provides a detailed description of how this reaction is conducted.

Procedure:
A 2.5 liter flask is charged with 800 g of chlorobenzene. With stirring, 123.2 g of 100% p-anisidine (preferably as melt) are then added. Then 102 g of acetic anhydride are added dropwise in the course of about 15 minutes, whereupon the temperature rises to 65° C. After stirring for 15 minutes at 65° C., the mixture is cooled to about 30° C. within about 10 minutes using a cooling bath, whereupon beige-coloured crystals of the acetanisidide begin to precipitate in the temperature range from about 45° C. The resultant suspension is slightly viscous, but readily stirrable. The addition of 800 g of 92% sulfuric acid is then commenced, with care being taken that the temperature does not much exceed 30°-40° C. The addition takes about 10 minutes. With further cooling, the addition of 101.2 g of 62.3% HNO3 is commenced immediately at a maximum temperature of 25° C. During the addition, the temperature can be allowed to rise to 20°-25° C. With the first few drops of HNO3 the emulsion starts becoming fluid immediately and the original blue colour changes to brown. The addition is complete after about 10 minutes and the batch is stirred for 20 minutes at 20° to 25° C. until the reaction is complete. Volume of the solution: about 1450 ml. The reaction mixture is then charged into a 2 liter separating funnel, whereupon a lower, dark-brown layer separates immediately. The upper, chlorobenzene layer is largely colourless or only a pale yellow colour. The lower layer is then passed slowly into a glass beaker, into which a mixture of 300 g of ice and water is stirred. The temperature is kept at around +5° C. by the constant addition of altogether about 1500 g of ice (duration c. 30 minutes). A thick yellow suspension is finally obtained. The suspension is stirred and then filtered. The filter cake is washed with 350 ml of ice-water, well pressed and, if desired, dried. Mother liquor and wash water are combined. The amount of chlorobenzene remaining in the separating funnel is about 760 g and, after replenishment to the original amount, can be re-used in the next batch. Yield: about 193 to 195 g of 4-acetamido-2-nitro-anisole in 99% purity. Melting point: about 150°-151° C.

Procedure:
To 600 g of polyphosphoric acid (117.2%) heated at 89° C. were added 1.2 g of 2,5-di(sulfamoylanilino)terephthalic acid followed by 12.0 g of 2,5-di[4-(N,N-diethylsulfamoyl)anilino]terephthalic acid. The mixture was stirred for five minutes, after which 120 g of 2,5-di(4-methylanilino)terephthalic acid were added over a period of approximately 45 minutes, the temperature being maintained below 105° C. by adjustment of the addition rate. The reaction mixture was held at 105° C. for five hours and then cooled to 94° C. To this mixture was added 92.8 g of phosphoric acid (75%) dropwise over a period of approximately 25 minutes. The resultant melt was allowed to stir for 15 minutes at 92° C. and then poured slowly into 1120 g of methanol, the temperature being maintained below reflux using a water bath. The slurry was allowed to cool to room temperature and stand for 16 hours. The pigment slurry was heated at reflux for one hour, cooled below 65° C., diluted with water, collected by filtration, and washed with water until free of acid. The resultant presscake was reslurried in water and heated to 45° C. An emulsion of 3.5 g of an anionic surfactant, 52.3 g of a petroleum distillate, and 120 g of water was added, and the slurry was stirred for three hours. The resultant slurry was collected by filtration and washed with water. The resultant wet cake can be dried or used as is for specific applications. Here, the wet cake was dried in an oven at 60° C. to give approximately 113 g of 2,9-dimethylquinacridone as a magenta pigment.

Procedure:
Sodium azide (1.95 g, 30 mmol) was added in small portions to a solution of 3,4-dihydro-1(2H)-naphthalenone (2.92 g, 20 mmol) in CH3SO3H (50 mL) at 0° C. The mixture was stirred at 0° C. for 15 min, 1 hr at room temperature, poured into ice (400 mL), basified until pH>8 with 1N NaOH at 0° C. and extracted with ether (3×100 mL).

Procedure:
In a four necked round bottom flask, under Argon atmosphere, 4-hydroxypiperidine (5.32 g, 52.6 mmol) was dissolved in CH2Cl2 (28 mL) and pyridine (28 mL). After cooling at 0° C., benzoyl chloride (6.4 mL, 55.2 mmol), dissolved in CH2Cl2 (7 mL) was drop wise added. The ice bath was removed and the mixture stirred 3 h at rt. The solid was filtered-off and the solvent removed under vacuum. Purification by typical column chromatography, eluting with CH2Cl2/MeOH (20:1) afforded the title compound (7.6 g, 70%) as pale yellow oil. Rf=0.21 (CH2Cl2/MeOH 20:1). MS (ESI) m/z: 206 [M−H]+.

Procedure:
0.4 Gram (1.1 mmol) of 4-methoxyimino-5-methyl-6-(1-ethyl-5-hydroxypyrazol-4-yl)carbonylthiochroman-1,1-dioxide corresponding to pyrazole derivative (I-H), 0.23 g (1.2 mmol) of phenacyl bromide corresponding to compound B-A-Hal and 0.15 g of potassium carbonate were added to 10 ml of acetone, and the mixture was stirred under heat for 8 hours. Insolubles were removed by filtration, and then the acetone was distilled off. The residue was dissolved in ethyl acetate, and the mixture was washed with a saturated sodium chloride aqueous solution and dried over sodium sulfate. The ethyl acetate was distilled off under reduced pressure, and the residue was subjected to column chromatography (hexane/ethyl acetate) to give 4-methoxyimino-5-methyl-6-(1-ethyl-5-phenacyloxypyrazol-4-yl)carbonylthiochroman-1,1-dioxide (Compound Ib-2) at a yield of 52%.
