Reaction Steps

To a suspension of 2-chloro-6-(cyclopentyloxy)-7-methoxyquinazoline (100.0 mg, 0.36 mmol) (obtained from the company compound collection) in 20 ml of CH3CN at room temperature was added the trans-4-aminocyclohexanol (207.0 mg, 1.79 mmol). The resulting mixture was heated to 60° C. for 5 hours. The reaction was cooled and partitioned with EA and water. The organics layer was washed with water (2×20 mL) and brine (20 mL), combined and dried over MgSO4, Removal of the solvent provided a yellow solid. The crude material was purified using silica gel eluting with 95/5 EA/MeOH to afford 45.9 mg of the desired product with 35.9% yield. 1H NMR (400 MHz, DMSO-d6) ppm 1.14-1.40 (m, 4H), 1.51-2.06 (m, 12H), 3.36-3.52 (m, 1H), 3.66-3.80 (m, 1H), 3.82-3.95 (m, 3H), 4.54 (s, 1H), 4.75-4.88 (m, 1H), 6.74 (d, J=8.06 Hz, 1H), 6.83 (s, 1H), 7.12 (s, 1H), 8.80 (s, 1H).
