Participants

Reaction Steps

2,3,4,5-Tetrahydro-1H-pyrido[4,3-b]indol-1-one (931 mg) was treated with sodium hydride (73% dispersion in oil; 328 mg) and was then stirred with 2-bromopropane (615 mg) at room temperature for 72 h. Purification by FCC eluting with System A (200:8:1) gave a foam (324 mg) which was further purified by recrystallisation from ethyl acetate: hexane (1:1) to give the title compound (249 mg), t.l.c. (System A, 100:8:1) Rf 0.58.
