Participants

Reaction Steps

The 9-methyl-3-tosyloxy-1,2,3,4-tetrahydrocarbazole was prepared from 49 g. of 3-hydroxy-9-methyl-1,2,3,4-tetrahydrocarbazole and 49 g. of tosyl chloride using the procedure described in Example 21 for the preparation of 6-methyl-3-tosyloxy-1,2,3,4-tetrahydrocarbazole. There was thus obtained 81 g. of 9-methyl-3-tosyloxy-1,2,3,4-tetrahydrocabazole which melted at 155°-157°C.
