PROCEDURE
实验过程
To a solution of tert-butyl 4-((benzyloxycarbonylamino)methyl)-4-(3-(dimethylcarbamoyloxy)phenylcarbamoyl)-piperidine-1-carboxylate from step C (0.245 g, 0.441 mmol) in MeOH (2 mL) was added 4 M HCl in dioxane (0.331 mL, 1.32 mmol). The reaction was heated at 50° C. for 1 hour, and then concentrated under vacuum, re-dissolved in MeOH and re-concentrated twice to give the title compound as the hydrochloride salt. MS (ES+) [M+H]+=455.
