Participants

Reaction Steps

A mixture of N—((R)-pyrrolidin-3-yl)cyclopropanecarboxamide (250 mg, 0.86 mmol), 2-(4-chloro-6-fluoroquinazolin-2-yl)phenol (250 mg, 0.86 mmol) and triethylamine (0.240 mL, 1.72 mmol) in CH2Cl2 (10 mL) was stirred at room temperature. The reaction was complete after one hour. The reaction was quenched with water, the aqueous layer was extracted twice with CH2Cl2, and the combined organic extracts were dried-over MgSO4, filtered, and concentrated. Purification via silica gel chromatography using 0-10% EtOAc/CH2Cl2 gave N—((R)-1-(6-fluoro-2-(2-hydroxyphenyl)quinazolin-4-yl)pyrrolidin-3-yl)cyclopropanecarboxamide (230 mg, 68%). LC/MS: m/z 393.3 (M+H)+ at 2.35 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)). 1H NMR (400 MHz, DMSO-d6) δ 8.42-8.46 (m, 2H), 8.03 (dd, J=10.5, 2.6 Hz, 1H), 7.88-7.92 (m, 1H), 7.74-7.79 (m, 1H), 7.35-7.39 (m, 1H), 6.92-6.96 (m, 2H), 4.44-4.47 (m, 1H), 4.01-4.28 (m, 3H), 3.83-3.87 (m, 1H), 2.20-2.28 (m, 1H), 1.99-2.06 (m, 1H), 1.51-1.57 (m, 1H), 0.63-0.73 (m, 4H) ppm.
