Procedure

The product of example 2a above, 2-phenoxy-6-aminobenzonitrile, (1.5 g, 7.14 mmol) was dissolved in dry tetrahydrofuran (50 mL) and stirred under argon in a room temperature water bath. Lithium aluminum hydride (0.53 g, 14.0 mmol) was added in portions over 10 minutes. The reaction mixture was heated to 60° C. for 1 hour. The reaction mixture was cooled to room temperature and anhydrous sodium sulfate was added followed by quenching by the addition of a freshly prepared saturated solution of anhydrous sodium sulfate. The solvent was evaporated and the residue triturated with ethyl acetate, filtered and evaporated. Flash chromatography on silica gel eluted with 0–3% methanol in methylene chloride gave the title compound as a white amorphous solid. Recrystallization from carbon tetrachloride, hexane gave a white crystalline solid. mp 69–71° C.
