Procedure

A suspension of 1-benzoyl-3-[3-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)-phenyl]-thiourea (241 mg, 0.530 mmol) in methyl alcohol (2.0 ml) and water (0.5 mL) is stirred at room temperature as sodium hydroxide (31 mg, 0.78 mmol) is added. The reaction mixture is heated to 50° C. for 17 h. The reaction mixture is concentrated to remove methyl alcohol. Water is added to the mixture and the solid is filtered, washed with water and dried to give 179 mg of [3-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)-phenyl]-thiourea, compound 767 (96% yield) as a white solid.
