Procedure

A solution of (R)-benzyl pyrrolidin-3-ylcarbamate oxalate (1.35 g, 4.38 mmol) in CH2Cl2 (5 mL) was added dropwise to a solution of 2-(4-chloro-6-fluoroquinazolin-2-yl)phenol (1.0 g, 3.6 mmol) and triethylamine (1.22 mL, 8.76 mmol) in CH2Cl2 (10 mL). After stirring the mixture for 2 h, the reaction was quenched with H2O, the layers were separated, and the aqueous layer was extracted with CH2Cl2. The combined organic extracts were dried over MgSO4, filtered, and concentrated. The residue was purified via silica gel chromatography using 5-10% EtOAc in CH2Cl2 to give (R)-benzyl 1-(6-fluoro-2-(2-hydroxyphenyl)quinazolin-4-yl)pyrrolidin-3-ylcarbamate (1.37 g, 82%). 1H NMR (400 MHz, CDCl3) δ 8.39 (d, J=6.9 Hz, 1H), 7.80 (s, 1H), 7.68 (d, J=8.5 Hz, 1H), 7.46 (m, 1H), 7.37 (m, 6H), 7.01 (d, J=7.8 Hz, 1H), 6.90 (t, J=7.5 Hz, 1H), 5.17 (m, 2H), 4.51 (s, 1H), 4.25 (m, 1H), 4.10 (m, 2H), 3.91 (m, 1H), 2.37 (m, 1H), 2.12 (m, 1H). LC/MS: m/z 459.5 (M+H)+ at 2.80 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
