Benzyl chloroformate → HCID 58386793, compound

Participants

Reaction Steps

To a solution of (3R,5R)-5-(tert-butyldimethylsilyloxy)piperidin-3-ol (1 eq) in 20 mL of 1,4-dioxane and 8 mL of water was added benzyl chloroformate (1.5 eq). The mixture was stirred at room temperature for 4 hours. The crude mixture was diluted with 100 mL of EtOAc, washed with brine, then dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The crude residue was purified by flash chromatography (EtOAc:hexanes=1:3) to yield (3R,5R)-benzyl 3-(tert-butyldimethylsilyloxy)-5-hydroxypiperidine-1-carboxylate (74%). LC/MS (m/z): 366.2 (MH+).
