Procedure

1-[1-(4-Cyanobenzoyl)-4-piperidinyl]-3,4-dihydrocarbostyril (1 g) is dissolved in chloroform (10 ml) and thereto is added ethanol (0.18 ml). Under ice cooling, hydrochloric acid gas is passed through the mixture to saturate and further the mixture is stirred at 5°-7° C. for 4 days. After the reaction, the solvent is concentrated to give 1-{1-[4-(1-ethoxy-1-iminomethyl)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (1 g). This product is used for the subsequent reaction.
