Reaction Steps

To a solution of (R)-neopentyl 1-(2-(2-fluoro-6-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-ylcarbamate (224 mg, 0.49 mmol) in CH2Cl2 (5 mL) was added a 2.0 M solution of HCl in ether (0.24 mL, 0.49 mmol). After the addition of ether (20 mL), a precipitate formed, which was filtered and dried under vacuum to give (R)-neopentyl 1-(2-(2-fluoro-6-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-ylcarbamate hydrochloride (HCl salt of compound 13) (225 mg, 94%). 1H NMR (400 MHz, DMSO-d6). LC/MS: m/z 453.3 (M+H)+ at 2.73 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
