Reaction Steps
28 ml of t-butyl bromoacetate and 1.4 g of tetra-n-butylammonium hydrogen sulphate in 10 ml of water are added to a solution of 30.1 g of N-benzyloxycarbonyl-4-hydroxy-piperidine in 300 ml of toluene. Thereafter, a solution of 125 g of sodium hydroxide in 125 ml of water is added dropwise thereto. After stirring overnight, the organic extracts are separated, dried and concentrated. After drying there are obtained 34.1 g of N-benzyloxycarbonyl-4-[(t-butoxy carbonyl) methoxy]-piperidine, Rf =0.76 (ethyl acetate). MS (EI): 293 (M-C4H8)+.
