Procedure
To a solution of (R)-tetrahydrofuran-3-yl((R)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperidin-3-yl)methylcarbamate (0.085 g, 0.18 mmol) in 9 mL CH2Cl2 was added dropwise a 2.0 M HCl solution in ether (0.09 mL, 0.18 mmol). Ether (20 mL) was then added, leading to the precipitation of (R)-tetrahydrofuran-3-yl((R)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperidin-3-yl)methylcarbamate hydrochloride which was filtered and dried (85 mg, 95%). LC/MS: m/z 463.5 (M+H)+ at 2.33 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
