Procedure:
A stirred mixture of 17.7 g of 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one (U.S. Pat. No. 4,281,000, Ex. 1) and 12.6 g of 4-amino-5-imidazolecarboxamide hydrochloride in 100 ml of glacial acetic acid was heated on a steam bath for 4 hours. The reaction mixture was then allowed to stand at room temperature for 16 hours. The mixture was evaporated to dryness in vacuo and the residual solid was partitioned between dichloromethane and saturated sodium bicarbonate. The two layers were separated, the organic layer was dried over anhydrous sodium sulfate and filtered and evaporation of the filtrate gave a dark yellow solid which was treated with isopropyl alcohol. This solid was collected by filtration and washed with hexane. The yellow solid was dried in vacuo to give 10.0 g of the product of the example, mp >260° C.

Procedure:
12.1 g (about 39.65 mmol) of the compound from Example 6A were initially charged in DMF (217 ml), and 8.25 g (43.62 mmol) of 2-fluorobenzyl bromide and 14.21 g (43.62 mmol) of caesium carbonate were then added. The mixture was stirred at RT for two hours. The reaction mixture was then added to water (1.17 l) and extracted twice with ethyl acetate (502 ml). The collected organic phases were washed with saturated aqueous sodium chloride solution (335 ml), dried, filtered and concentrated. The residue was chromatographed on silica gel (mobile phase:petroleum ether/ethyl acetate 97:3) and the product fractions were concentrated. This gave 9.0 g (61% of theory) of the title compound as a solid. The solid was taken up in ethyl acetate and washed with 10% strength aqueous sodium thiosulphate solution and then with saturated aqueous sodium chloride solution, dried and concentrated.

Isopropanol (20 ml) was added and the mixture stirred for 17 h before the solvent was removed in vacuo to give a residue that was purified by Biotage. Elution with dichloromethane-EtOH-ammonia (325:8:1) followed by solvent evaporation in vacuo gave the title compound (1.13 g). LCMS RT=3.85 min, ES+ve 663 (MH)+.

Procedure:
According to Japanese Examined Patent Publication (Kokoku) No. Hei 3-31715, sodium methoxide (0.27 g) was added to a solution of 2-(3-nitrobenzylidene)acetoacetic acid isopropyl ester (1.39 g) and amidinoacetic acid (1-benzhydryl-3-azetidinyl) ester acetate (1.62 g) in isopropyl alcohol (80 ml) and the mixture was heated under reflux for 4 hours. After the reaction mixture was cooled, insoluble material was removed and the solvent was evaporated under reduced pressure. The thus obtained residue was dissolved in ethyl acetate and the mixture was washed with water, followed by drying over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was subjected to silica gel column chromatography (toluene:ethyl acetate=3:1) to obtain pale yellow (±)-2-amino-1,4-dihydro-6-methyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylic acid 3-(1-diphenylmethylazetidin-3-yl) ester 5-isopropyl ester (2.17 g, 74%).
