Procedure

A cooled (−78° C.) solution of 6-(1-benzyl-5-methoxy-1H-indol-3-yl)-5H-pyrrolo[2,3-b]pyrazine [50 mg, Example 1(m)] in tetrahydrofuran (20 mL) was treated with liquid ammonia (20 mL) then with sodium (100 mg). After stirring at −78° C. for 30 minutes the reaction mixture was allowed to warm slowly to ambient temperature, then treated with water (50 mL) and then extracted three times with ethyl acetate (50 mL). The combined extracts were dried over sodium sulfate and then evaporated. The residue was triturated with diethyl ether to give the title compound (14 mg) as a brown solid, m.p. 268-271° C. MS: 265.24 (MH+).
