To a vigourously stirred solution of 10 g of carbazole in 50 ml of acetone, 10 ml methyl sulphate was added, followed by dropwise addition of a solution of 10 g NaOH in 7 ml water. After a few minutes the solution was poured into water. N-methyl carbazole was purified by two ethanol recrystallization, extraction with boiling petroleum ether and another ethanol recrystallization (yield 90% m.p.=88° C.).
