Reaction Steps

To a solution of (R)-2-(3-(6-(2-fluorophenyl)-5,6-dihydrobenzo[h]quinazolin-2-ylamino)phenyl)ethanol (4.59 g, 11.17 mmol) in dichloromethane (50 mL) was added triethylamine (2.33 mL, 16.75 mmol) and methanesulfonyl chloride (0.95 mL, 12.28 mmol). The mixture was stirred at room temperature for 1 h, washed with water (60 mL×3), dried over sodium sulfate and concentrated to yield the title compound as a yellow solid (5.37 g, 98% yield). 1H-NMR (DMSO-d6) δ 9.59 (s, 1 H), 8.37-8.35 (dd, 1 H), 8.33 (s, 1 H), 7.80 (s, 1 H), 7.71 (d, J=10.4 Hz, 1 H), 7.54-7.45 (m, 2 H), 7.29-7.22 (m, 3 H), 7.07-7.02 (m, 2 H), 6.82-6.78 (m, 2 H), 4.67 (t, J=6.8 Hz, 1 H), 4.45 (t, J=6.8 Hz, 2 H), 3.22-3.08 (m, 2 H), 3.13 (s, 3 H), 3.01 (t, J=6.4 Hz, 2 H). LCMS m/e 490 [M+H].
