To a solution of (S)-tetrahydrofuran-3-yl (R)-1-(2-(2-fluoro-6-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-ylcarbamate (160 mg, 0.35 mmol) in 2 mL CH2Cl2 was added 2 M HCL solution in ether (0.176 mL, 0.35 mmol) resulting in precipitation of a solid. After the addition of 10 mL ether, the reaction was stirred for 30 minutes, filtered and the resulting solid was dried to obtain (S)-tetrahydrofuran-3-yl (R)-1-(2-(2-fluoro-6-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-ylcarbamate hydrochloride (130 mg, 76%)). LC/MS: m/z 453.3 (M+H)+ at 2.13 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)). 1H NMR (400 MHz, DMSO-d6) δ 8.29 (s, 1H), 7.57 (s, 2H), 7.43-7.49 (m, 1H), 6.83-6.89 (m, 2H), 5.08 (s, 1H), 4.23-4.42 (m, 4H), 3.62-3.73 (m, 5H), 2.24-2.34 (m, 1H), 2.04-2.11 (m, 2H), 1.86-1.92 (m, 1H) ppm.
