Procedure
100 g. (0.5 mole) of 6-methyl-1,2,3,4-tetrahydrocarbazol-1-one and 500 ml. (4 mole) of ethylene chloride are stirred together with 500 ml. of aqueous sodium hydroxide solution (30% strength) and 4.25 g. (12.5 m moles) of tetrabutylammoniumhydrogen sulfate for 20 hours at 20° to 30° C. Working up is done according to the procedure given in Example 1. 112 g. (=86% of the theoretical) of 6-methyl-9-(2-chloroethyl)-1,2,3,4-tetrahydrocarbazol-1-one (melting at 108° C.) are thus obtained.
