5765-44-6, To a solution of 5-methyl isoxazole (5.0 g) in ethyl acetate (100 ml), N-bromo succinate imide (23.6 g) and 2,2′-azobisisobutyronitrile (200 mg) were added to the mixture, and the mixture was refluxed overnight under nitrogen atmosphere. After cooling to 0C, the insolubles were filtered off, the filtrate was washed with an aqueous solution of sodium thiosulfate and saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was separated and purified by silica gel column chromatography (hexane:ethyl acetate = 10:1), to give 5-bromomethyl isoxazole (1.0 g) as oil. 1H-NMR (200 MHz, CDCl3) delta 4.50 (2H, s), 6.34 (1H, d, J = 1.8 Hz), 8.23 (1H, d, J = 1.8 Hz)

EXAMPLE 1 Ethyl 2-amino-5-cyano-6-methyl-4-(3-phenyl-1,7-naphthyridin-5-yl)-1,4-dihydropyridine-3-carboxylate STR24 2 g (8.5 mmol) of 3-phenyl-1,7-naphthyridine-5-carboxaldehyde are suspended in 20 ml of ethanol and stirred with 0.7 ml (8.5 mmol) of 5-methylisoxazole. A solution of 196 mg of sodium in 14 ml of ethanol is added and the mixture is stirred for 2 hours at 50 C. 1.42 g of ethyl amidinoacetate hydrochloride and 0.51 ml (8.5 mmol) of acetic acid are added and the mixture is boiled for 16 hours. After cooling, 10 g of silica gel are added and the mixture is concentrated in vacuo. The residue is chromatographed on a silica gel column using toluene/ethyl acetate mixtures. After concentration of the pure fractions, the product is crystallized by trituration with ether. 2 g of crystals are obtained.
