Procedure

In a manner as that described in Example 62, 3,4-dimethoxy-6,7-dihydro-5H-benzocycloheptene-8-carboxylic acid and 1-(3,4,5-trimethoxy-benzoyl)piperazine are subjected to amidation to give 1-(3,4-dimethoxy-6,7-dihydro-5H-benzocyclohepten-8-ylcarbonyl)-4-(3,4,5-trimethoxybenzoyl)piperazine. This product is recrystallized from ethyl acetate to give colorless prisms, m.p. 133°-134° C.
