Procedure
1.0 g of ethyl 3-(2-cyano-4-pyridyl)-2-isopropoxypropanoate was dissolved in 70 mL ethanol, and 1.9 mL conc. hydrochloric acid and 0.9 g of 10% palladium-carbon were added thereto, and the mixture was stirred at room temperature for 2 hours in a hydrogen atmosphere. After the catalyst was filtered off and the solvent was evaporated, the reaction product was subjected to azeotropic distillation with ethyl acetate and toluene, to give 1.21 g of ethyl 3-[2-(aminomethyl)-4-pyridyl]-2-isopropoxypropanoate hydrochloride was obtained as a crude product.
