Reaction Steps

(3R,5R)-3-tert-Butoxycarbonylamino-5-methyl-piperidine-1-carboxylic acid benzyl ester (3.25 g, 9.327 mmol) was dissolved in DCM (50 ml) and HCl 4M in dioxane (20 ml, 80 mmol) was added. The resulting colorless solution stirred at RT for 4 hours before being evaporated. The residue was dried under high vacuum overnight to give 2.89 g of (3R,5R)-3-amino-5-methyl-piperidine-1-carboxylic acid benzyl ester hydrochloride as a white foam (>95% yield).
