Procedure

A mixture 130 mg (0.302 mmole) of 1-(2-bromo-4-isopropylphenyl)-3-cyano-6-methyl-4-phenyl-7-azaindole (Example 66) and 10 mL of 65% sulfuric acid were refluxed for one hour. The mixture was poured onto ice, Conc. ammonium hydroxide was added until the mixture was basic to pH paper. The mixture was extracted with ethyl acetate. The extract was evaporated and chromatographed on silica gel with 70:30 hexane-ethyl acetate. There was obtained 112 mg (92% yield) of 1-(2-bromo-4-isopropylphenyl)-6-methyl-4-phenyl-7-azaindole. Mass spec: (m+H)+=405.10; calculated, 405.10.
