To a solution of morpholin-4-yl-(3-nitro-5-(trifluoromethyl)phenyl)methanone (304 mg, 1.0 mmol) in 15 mL of THF was added lithium aluminum hydride (152 mg, 4 mmol) in THF (7 mL) under nitrogen. The dark colored solution was refluxed for 2 hours and then cooled. NaOH solution was added (0.5 N, 15 mL) dropwise. The basic solution was washed with methylene chloride (3×40 mL) and the pooled organic layers were washed with HCl solution (5%). The aqueous layer was separated, basified with NaOH to pH 8, and extracted with ethyl acetate. The ethyl acetate solution was dried over anhydrous Na2SO4. The solution was used in further reactions without further work-up.
