실험 절차

Sodium hydride (60% dispersion in oil; 196 mg) was added to a stirred suspension of 6-fluoro-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-1-one (500 mg) in dry DMF (10 ml) under nitrogen. After 30 min the solution was cooled (0°), and methyl iodide (0.153 ml) was added. After stirring for 15 min the suspension was poured into water 950 ml) and extracted with dichloromethane (3×25 ml). The combined, dried organic extracts were evaporated to give a solid (ca. 530 mg) which was purified by FCC eluting with System A (250:10:1) to give the title compound (130 mg), m.p. 242°.
