Reaction Steps

(5R)-3-(4-(4-Oxopiperidin-1-yl)-3-fluorophenyl)-5-(1,2,3-triazol-1-ylmethyl)oxazolidin-2-one (250 mg, 0.70 mM) was dissolved in a mixture of anhydrous tetrahydrofuran (5 ml) and dichloromethane (5 ml) under nitrogen. Acetic acid (1 drop), methylamine (33% solution in methanol, 31 μL, 0.77 mM) and sodium acetoxyborohydride (222 mg, 1.05 mM) were added, and the mixture stirred at ambient temperature for 3 hours. The mixture was diluted with water (15 ml) and dichloromethane (15 ml), and the pH adjusted to 9 by addition of triethylamine. The organic phase was separated, washed with water (2×15 ml), brine (15 ml), and dried (magnesium sulfate). Evaporation gave the desired product (145 mg).
