Slow addition of isocyanate (X=0) or isothiocyanate (X=S) XXI (R 4 -N=C=X) , at a reaction temperature of preferably from about -20°C to about 25°C provides the cyclized product II where R 2 is an appropriate cation, such as K * . The anionic intermediate may be treated with acid to obtain compounds of formula I where R 2 is H. The anionic intermediate may be treated with an appropriate electrophile, R 2 -L' , where L' is an appropriate leaving group, such as halogen, mesylate, tosylate and the like, to obtain compounds of formula I where R 2 is other than H as defined above. The starting materials, R 2 -L', R n -CH 2 -C (0) -L and R 12 - CN, are commerically available or readily prepared from commercially available starting materials using processes and reagents well known in the art. N- substituted isocyanates or N-substituted isothiocynates (R 4 -N=C=X) are commercially available or are readily prepared by treatment of R.-L, where L is an appropriate leaving group (such as halogen, mesylate, tosylate and the like) , with sodium or potassium cyanate or thiocyanate; from the corresponding amino (R 4 -NH2) compounds, for example, by reaction with phosgene, thiophosgene, carbon disulfide and the like in an appropriate solvent; from the corresponding acyl azide (R 4 -C(0)-N 3 ) compounds (Curtius Rearrangement) in an appropriate solvent; and the like. The following Examples are presented for illustrative purposes only and are not intended, nor should they be construed, as limiting the invention in any manner. Those skilled in the art will appreciate that modifications and variations of the compounds disclosed herein can be made without violating the spirit or scope of the present invention. EXAMPLES Example 1 Procedure for the preparation of 3 -methyl -2 -methyl thio- 5- ( 3 -me thy lpheny 1 ) -6- (4-pyridyl ) -4 (3H) -pyrimidinone A solution of potassium t-butoxide (IM in t-butanol, 11, 1 mol) was added dropwise to a stirred solution of ethyl 3-methylphenyl acetate (178 g, 1 mol) in N, N- dimethylform.amide (2 1). A solution of 4-cyanopyridine (104.11 g, 1 mol) in N, N-dimethylformamide (1 1) was pumped into the reaction mixture over a period of about 4.5 h. The mixture was then stirred at room temperature for 3 h, before the dropwise addition of a solution of methyl isothiocyanate (68.4 ml, 1 mol) in N, N- dimethylformamide (50 ml) over a period of 10 min. After stirring for 1 h at room temperature, the reaction mixture was cooled to 3°C and methyl iodide (62.3 ml, 1 mol) was added dropwise over a period of 10 min. Stirring was continued at room temperature overnight. The mixture was cooled to 3°C and water (4 1) was pumped into the reaction mixture over a period of 6 h. The precipitate was removed by filtration, washed with water and dried in a vacuum oven to give 3-Methyl-2- methylthio-5- (3-methylpheny1) -6- (4-pyridyl) -4 (3H) - pyrimidinone as a solid: MS (m/z) : 324 (M+H) * ; C 18 H 17 N 3 OS requir. 323.4. Example 2 Procedure for the preparation of 3 -methyl -2 -methyl thio - 5- (3-trifluoromethylphenyl) -6- (4 -pyr idyl) -4 (3H) - pyrimi dinone Step A: Ethyl 3-trifluoromethylphenylacetate : To a mixture of 3-trifluoromethylphenylacetic acid (500 gm, 2.45 mol) in absolute ethanol (11) was added cone, sulfuric acid (10 mL) at room temperature. The reation was heated to reflux for 12 hr, cooled to room teperature and the ethanol was removed in vacuo . The acid was neutralized by the addition of 500 mL of saturated NaHC0 3 and extracted with ethyl actetate. The combined organic extracts were dried (Mg 2 S0 4 ) , filtered and concentrated to give the Step A compound: Silica gel TLC eluted with 20% ethyl actetate/hexanes ; Rf = 0.65. Step B: 3-methyl-2-methylthio-5- (3- trifluoromethylphenyl) -6- (4-pyridyl) -4 (3H) -pyrimidinone; A solution of potassium t-butoxide (IM in t-butanol, 323 mL, 323 mmol) was added dropwise to a heated (40 °C) , stirred solution of ethyl 3-trifluoromethylphenyl acetate (75 g, 323 mol) in N, N-dimethylformamide (431 mL) . A solution of 4-cyanopyridine (33.6 g, 323 mmol) in N, N-dimethylformamide (431 mL) was pumped into the reaction at a rate of 1.4 mL/min. After complete addition, the mixture was stirred for 30 min, and cooled to room temperature before the dropwise addition of a solution of methyl isothiocyanate (22.1 mL, 323 mmol) over a period of 50 min. After stirring for 50 min at room temperature, the reaction mixture was cooled to 3°C and methyl iodide (20.1 mL, 323 mol) was added dropwise over a period of 10 min. Stirring was continued at room temperature overnight. The solvents were removed in vacuo, and the residue was pre-absorbed on silica gel, loaded on a column, and the product was isolated by chromatography (Si0 2 , gradient of 10% to 40% acetone/hexane) to give 3-methyl-2-methylthio-5- (3- trifluoromethylphenyl) -6- (4-pyridyl) -4 (3H) -pyrimidinone: silica gel TLC eluted with 10% methanol/methylene chloride, Rf = 0.6. Although the above examples illustrate syntheses in which R 11 is a substituted phenyl and R 12 is 4-pyridyl, this approach may be equally applied to any other aryl or heteroaryl ring within the definitions of R u and R 12 by the appropriate choice of the starting material . Some of the sustituents of R 11 and R 12 may require appropriate protection prior to reaction, such as hydroxy, thiol, carboxy, amido, amino and the like radicals may be reacted analogously preferably after appropriate protection. For example, a hydroxy, thiol or carboxy radical may be protected with a benzyl radical that can be remove after reaction, or an amine or amide nitrogen may be protected with e.g. a tert- butyldimethylsilyloxymethyl group (Benneche et al . , Acta Chem . Scand. B 42 384-389 (1988)), a tert- butyldimethylsilyl group, a benzyloxymethy1 group, a benzyl group or the like (PJ . Removal of the protecting group P 1 of the resulting pyrimidinone with a suitable reagent ( e . g. , tetrabutylammonium fluoride in the case where P. is t-butyldimethyl-silyloxymethyl) . The foregoing is merely illustrative of the invention and is not intended to limit the invention to the disclosed compounds. Variations and changes which are obvious to one skilled in the art are intended to be within the scope and nature of the invention which are defined in the appended claims. From the foregoing description, one skilled in the art can easily ascertain the essential characteristics of this invention, and without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions .
