Ethylamine → 3-(Ethylamino)-1,2,3,4-tetrahydrocarbazole

Participants

Reaction Steps

Following the procedure given in Example 18 and using 25 g. of 3-tosyloxy-1,2,3,4- -tetrahydrocarbazole and 90 g. of ethylamine there was otained 3 g. of 3l -(ethylaino)-1,2,3,4-tetraydrocarbazole which melted at 128°-129°C. (corr.). Alternatively this compound can be prepared by reduction of 3-acetamido-1,2,3,4-tetrahydrocarbazole (Example 2) with lithium aluminum hydride following a procedure similar to that described in Example 260 below.
