HCID 129915971,4-Bis[5-(4-methylthiophenyl)-2-pyridyl]hexahydro-1,4-diazepineYield 43.7%

Procedure

Following the procedure of Example 1, crude crystals were obtained from the 1,4-bis(5-bromo-2-pyridyl)hexahydro-1,4-diazepine (206.0 mg, 0.500 mmol) synthesized in Reference Example 1 and 4-methylthiophenylboronic acid (202.0 mg, 1.20 mmol). The crude crystals were recrystallized from chloroform-hexane to yield the title compound as pale yellow needles (melting point: 252.0-255.0° C.) (109.0 mg, yield: 43%).
