反応手順

A mixture of 5.4 g (0.02 mole) of 3-(4-chlorophenyl)-1,2-dimethyl-1H-indole-5-ol, and 5.1 g (0.03 mole) of 2-bromo-2-methyl-propanoic acid was heated for two hours to 90°-130° C. Subsequently the mixture was taken up in chloroform/methanol (8:2) and chromatographed on silicagel. The evaporation residue of the eluate was stirred with cyclohexane and suction filtered.
