반응 단계

To a solution of 4-piperazinobenzofurano[3,2-d]pyrimidine (200 mg, 0.79 mmol) and pyridine (0.5 mL, 7.9 mmol) in dichloromethane (20 mL) was added a solution of product 1d in dichloromethane (20 mL) and this was stirred overnight. Methanol was added to quench excess thiophosgene; and the residue after removal of solvent was purified by silica gel column chromatography eluting with 5% methanol/dichloromethane and further recrystallized from dichloromethane/hexane to give 150 mg (37%).
