Reaction Steps

Ethyl 2-amino-3-oxo-3-(4-(trifluoromethyl)phenyl)propanoate hydrochloride (20.00 g, 64.17 mmol), was prepared as described by Singh, J., Tetrahedron Letters 34 (2), 211-214 (1993), was charged into a 500 mL round-bottomed flask and mixed with MeOH (160 mL). Sodium borohydride (3.641 g, 96.25 mmol) was added to the above mixture slowly at 0° C. The cooling bath was removed after the addition. The mixture was stirred at room temperature for 2 hours, and then filtered through a silica gel column in a funnel. The silica gel was washed with 10% MeOH (2.0M NH3)—CH2Cl2. The filtrate was concentrated in vacuo, and the crude product was triturated with 25% EtOAc-Hexane to provide the pure product as a white solid. LCMS (API-ES) m/z (%): 278 (M++H).
