To a solution of (2S)-2-(4-aminophenyl)-4-((1R)-1-phenylethyl)morpholine (17.45 g, 61.8 mmol) and ammonium formate (11.7 g, 185.4 mmol) in mixture of tetrahydrofuran (180 ml), methanol (180 ml) and water (45 ml) was added 10% palladium on carbon (wet, 1.8 g) and the mixture was stirred at 95° C. for 3 hours. After filtration, the solvent was removed in vacuo and the residue was partitioned between water and dichloromethane. The organic layer was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure to give 4-((2S)-morpholin-2-yl)phenylamine (10.45 g, 95%) as pale yellow crystals.
