Reaction Steps

To a solution of trans-N-[8-(tetrahydro-2H-pyran-4-yloxy)quinazolin-2-yl]cyclohexane-1,4-diamine (0.3 g, 0.876 mmol) and acetyl chloride (0.0825 g, 1.05 mmol) in CH2Cl2 (10 mL) was added Et3N (0.106 g, 1.05 mmol). The resulting mixture was stirred at room temperature overnight. TLC (DCM:MeOH=10:1) showed the reaction was complete. CH2Cl2 (30 mL) was added to the solution. The solution was washed with H2O (3×20 mL) and brine (30 mL), dried over Na2SO4 and concentrated in vacuo to give crude solid, which was washed with ethyl acetate to give the title compound (0.180 g, 54.5%) as a white solid. 1H NMR (CDCl3, 400 Hz): 8.875 (s, 1H), 7.255 (d, 2H), 7.132 (d, 1H), 7.050 (t, 1H), 5.245 (d, 1H), 5.133 (d, 1H), 4.002 (m, 2H), 3.869 (m, 1H), 3.709 (m, 1H), 3.507 (m, 2H), 2.178 (d, 2H), 1.979 (t, 4H), 1.893 (m, 5H), 1.249 (m, 4H).
