Reaction Steps

3.3 g (16 mmol) of (2-(5-methyl-3-isoxazolyl)amino)nicotinaldehyde was dissolved in ethanol (60 mL), and 3.9 g (24 mmol) of diethyl malonate and 0.56 g (6.5 mmol) of piperidine were added thereto. The resulting mixture was stirred overnight at 90° C. The reaction mixture was cooled, and then the solvent was distilled off. The residue was purified by column chromatography (ethyl acetate:n-hexane=1:4 to 7:3), and thus 2.7 g of the title compound was obtained as pale yellow crystals (yield: 55%).
