Reaction Steps

To a solution of 4-benzyl aniline (200 mg, 1.1 mmol) in dichloroethane (1.5 mL) was added a solution of N-(t-butoxycarbonyl)-D-prolinal (239 mg, 1.2 mmol) in dichloroethane (1.5 mL) at 0-5° C. Sodium triacetoxyborohydride (393 mg, 1.85 mmol) was added to the above solution. Acetic acid (65 mg, 1.1 mmol) in dichloroethane (1 mL) was added dropwise, over a period of 5 min at 0-5° C. The reaction mixture was stirred at 0-10° C. for 3 h. The mixture was diluted with saturated aq NaHCO3 and extracted with dichloromethane. Organic layer was dried over anhy. MgSO4 and the solvent was removed in vacuo to obtain the crude mixture, which was purified by silica gel flash chromatography to obtain the title product (340 mg, 85%).
