Reaction Steps

4-Fluorobenzylamine (3.00 mL, 26.2 mmol), pyruvic aldehyde dimethyl acetal (3.11 mL, 26.2 mmol), DCE (87 mL), and sodium triacetoxyborohydride (7.79 g, 36.7 mmol) were stirred at ambient temperature. After 14 hours, the reaction was complete as indicated by LCMS. To the reaction mixture was added 30% aqueous K3PO4 (pH=14; 60 mL). The layers were partitioned and the aqueous layer was, extracted with EtOAc (2×50 mL), and washed with brine (60 mL). The organic portion was dried (Na2SO4), filtered, and concentrated to give the title compound (5.83 g, 25.7 mmol, 98% yield). MS (DCI/NH3) m/z 228 (M+H)+.
