Reaction Steps

Under an N2 atmosphere, Pd/C (10% weight, 140 mg) was added to a solution of (R)-benzyl 1-(6-fluoro-2-(2-hydroxyphenyl)quinazolin-4-yl)pyrrolidin-3-ylcarbamate (1.37 g, 5.3 mmol) in MeOH (10 mL). After purging twice with N2 and evacuating the atmosphere in the flask containing the reaction mixture, the reaction was stirred under an H2 atmosphere overnight. The mixture was filtered through a pad of Celite, and the filtrate was concentrated under reduced pressure to obtain (R)-2-(4-(3-aminopyrrolidin-1-yl)-6-fluoroquinazolin-2-yl)phenol (940 mg, 98%). 1H NMR (400 MHz, CDCl3) δ 8.41 (m, 1H), 7.73 (m, 2H), 7.40 (m, 1H), 7.28 (m, 1H), 6.94 (m, 1H), 6.85 (m, 1H), 4.15 (m, 2H), 3.99 (m, 1H), 3.77 (m, 1H), 3.68 (m, 1H), 2.20 (m, 1H), 1.86 (m, 1H) ppm. LC/MS: m/z 325.3 (M+H)+ at 1.68 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
