To tert-butyl 1-((2R,5S)-2,5-dimethylpyrrolidine-1-carbonyl)cyclopentylcarbamate (170 mg, 0.548 mmol) was added a 4.0 M dioxane solution of hydrogen chloride (0.137 mL, 0.548 mmol). The mixture was stirred at 23° C. for 64 h then concentrated. The residue was taken up in ether (10 mL). The precipitate was collected by filtration, rinsed with ether, and dried to provide the title compound as a white solid.
