To a mixture of (S)-tetrahydrofuran-3-yl(R)-1-(6-fluoro-2-(2-hydroxyphenyl)quinazolin-4-yl)pyrrolidin-3-ylcarbamate (250 mg, 0.57 mmol) and CH2Cl2 (25 mL) was added a 2.0 M HCl solution in ether (0.285 mL, 0.57 mmol). After the addition of ether (40 mL), the reaction was stirred for 1 h. The resulting solid was filtered and dried to afford (S)-tetrahydrofuran-3-yl(R)-1-(6-fluoro-2-(2-hydroxyphenyl)quinazolin-4-yl)pyrrolidin-3-ylcarbamate hydrochloride. LC/MS: m/z 439.5 (M+H)+ at 2.25 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)). 1H NMR (400 MHz, DMSO-d6) δ 8.18 (dd, J=8.1, 1.4 Hz, 1H), 8.00 (d, J=9.6 Hz, 1H), 7.90-7.94 (m, 1H), 7.78-7.83 (m, 1H), 7.45-7.49 (m, 1H), 7.00-7.03 (m, 2H), 5.10 (s, 1H), 4.09-4.25 (m, 4H), 3.90-3.92 (m, 1H), 3.62-3.75 (m, 4H), 2.22-2.27 (m, 1H), 2.03-2.14 (m, 2H), 1.83-1.91 (m, 1H).
