Procedure
Tert-butyl benzyloxy(4-cyanobutyl)carbamate was dissolved in a solution of 4 M HCl in 1,4-dioxane and the mixture was stirred for 18 h at room temperature. The solvent was removed under reduced pressure and the residue was treated with ethyl acetate and diethyl ether. A solid formed which was washed with diethyl ether, filtered and dried under high vacuum to give 1-(benzyloxy)piperidin-2-imine hydrochloride as a pale yellow solid.
