Reaction Steps

Sodium hydride (60% dispersion in oil; 196 mg) was added to a stirred solution of 8-fluoro-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-1-one (500 mg) in dry DMF (20 ml) at 21° under nitrogen. After 15 min, the solution was cooled (0°) and a 10% (v/v) solution of methyl iodide in DMF (1.6 ml) was added dropwise. After 10 min, water (150 ml) was added and the mixture was extracted with ethyl acetate (3×50 ml). The combined organic extracts were washed with water (3×50 ml), then brine (100 ml) and evaporated to give a solid which was purified by FCC Eluting with dichloromethane:methanol (80:1) to give the title compound (240 mg), m.p. 200°-202°.
