Participants

Reaction Steps

To a solution of tetrahydrofuran-3-ol (337 mg, 3.83 mmol) in THF (5 mL) was added NaH (153 mg, 60% disp. in oil, 3.83 mmol) and the mix stirred at r.t. for 20 min., forming a pale suspension. To this was added trans-4-[(7-fluoroquinazolin-2-yl)amino]cyclohexanol (100 mg, 0.383 mmol) and a yellow suspension formed almost immediately. The suspension was stirred at r.t. for 30 min then heated to 45° C. for 1 hour, then heated to 65° C. for 30 min then cooled to R.T. overnight. The liquors were concentrated and diluted with water (10 mL) and EtOAc (25 mL) and shaken vigorously. The aq. was removed and the organics washed with water (10 mL), brine (10 mL), dried over MgSO4, filtered and stripped to an oil. Purified by prep TLC eluting with EtOAc to yield the title compound as a white foam, 36 mg, 29%. 1H NMR (400 MHz, DICHLOROMETHANE-D2) δ ppm 8.75 (1H, s) 7.53 (1H, d, J=8.84 Hz) 6.62-6.88 (2H, m) 5.18 (1H, d, J=7.83 Hz) 5.05 (1H, s) 3.81-4.08 (5H, m) 3.54-3.79 (2H, m) 2.22-2.43 (1H, m) 2.08-2.21 (3H, m) 1.91-2.07 (2H, m) 1.36-1.51 (4H, m) 1.19-1.38 (4H, m); MS (API+) for C18H23N3O3 m/z 330.2 (M+H)+.
