The procedure described in Example 31 was employed. From 1,4-bis(5-bromo-2-pyridyl)hexahydro-1,4-diazepine (115.0 mg, 0.280 mmol) synthesized in Reference Example 1 and 3-benzyloxy-4,5-dimethoxyphenylboronic acid (170.0 mg, 0.590 mmol) synthesized from methyl 3-hydroxy-4,5-dimethoxybenzoate (Indian J. Chem., 21B, 27–29, (1982)) by a similar procedure to that described in Reference Example 8, 1,4-bis[5-(3-benzyloxy-4,5-dimethoxyphenyl)-2-pyridyl]hexahydro-1,4-diazepine was obtained as a colorless viscous oil (173.0 mg, yield: 84%). From 1,4-bis[5-(3-benzyloxy-4,5-dimethoxyphenyl)-2-pyridyl]hexahydro-1,4-diazepine (157.0 mg, 0.210 mmol), 1,4-bis[5-(3-hydroxy-4,5-dimethoxyphenyl)-2-pyridyl]-hexahydro-1,4-diazepine was obtained as a colorless oil (97.0 mg, yield: 84%).
