Procedure
By similar procedures applied in Example 2, from 3.00 g (5.19 mmol) of 1,3-bis [4-(4-bromobenzoyl)-1-piperazinyl]propane and 3.00 g (12.5 mmol) of 3,5-dimethoxy-4-propoxyphenylboronic acid, 4.20 g of 1,3-bis[4[4-(3,5-dimethoxy-4-propoxyphenyl) benzoyl]-1-piperazinyl]propane was obtained as a colorless oil (quantitative yield).
