Versuchsvorschrift

To a solution of 6,7-dimethoxy-4-piperazino-9H-pyrimido[4,5-b]indole (200 mg, 0.64 mmol) and pyridine (0.5 mL, 6.4 mmol) in dichloromethane (20 mL) was added a solution of product 1d in dichloromethane (20 mL) and the mixture 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 was further recrystallized from dichloromethane/hexane to give 50 mg (16%).
