Procedure
3,5-Dichlorobenzyl 4-((tert-butoxycarbonyl)amino)piperidine-1-carboxylate (step 1) (3.53 g, 8.75 mmol) was dissolved in DCM (20 ml). 4M HCl in dioxane (22 ml, 88 mmol) was added which resulted in the formation of a white solid. After gas evolution ceased, DCM (20 ml) was added and the reaction mixture was stirred vigorously for 4 hrs. The resulting mixture was filtered and the white solid was dried in a vacuum oven under reduced pressure to afford the title compound as a hydrochloride salt;
