trans-(4-Pyrrolidin-1-yl-tetrahydro-pyran-3-yl)-carbamic acid tert-butyl ester (intermediate H, 345 mg, 1.28 mmol) was dissolved in 6.4 mL dioxane. Hydrochloric acid (4N in dioxan, 3.2 mL, 13 mmol) was added. The reaction mixture was stirred at room temperature for 3 h. The solvent was evaporated off. The crude material, light brown solid (378 mg, >100%), MS: m/e=171.2 [(M+H)+] was used without further purification.
