Procedure

1-Ethyl-2-(4-hydroxy-3-nitrophenyl)-6-methoxy-1H-indole-3-carbonitrile (369 mg, 1.1 mmol), prepared as in example 1Gd, is combined with EtOAc (20 mL) and Pd/C (150 mg, 10%). This mixture is hydrogenated at 30 p.s.i. for 1 h. This is filtered through celite. The filtrate is concentrated and triturated with ether to yield 2-(3-amino-4-hydroxyphenyl)-1-ethyl-6-methoxy-1H-indole-3-carbonitrile (307 mg, 91%), compound 322, as a white solid.
