Procedure
According to the same manner as that described in Reference Example 5, 4-(3,4-dimethoxyphenyl)-3-hexanoyl-6,7-dimethoxy-2-methylquinoline was brominated with N-bromo-succinimide (NBS) to give 2-bromomethyl-4-(3,4-dimethoxy-phenyl)-3-hexanoyl-6,7-dimethoxyquinoline- This compound was recrystallized from ethyl acetate-hexane to give colorless prisms. mp. 146°-147° C.
