Procedure
1-{1-[4-(3-Aminopropoxy)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (0.5 g), methylisocyanate (0.15 ml) and acetone (10 ml) are heated at 100° C. for 18 hours in an autoclave. Acetone is distilled off and the residue is purified by silica gel column chromatography (solvent: methylene chloride:methanol=100-50:1) to give 1-{1-[4-(3-(3-methylureido)propoxy)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (0.19 g).
