실험 절차
Into a 1-neck round-bottom flask were added 2-[3-({5-chloro-4-[(3-methoxybenzyl)amino]pyrimidin-2-yl}amino)phenyl]ethanol (0.20 g, 0.52 mmol) and dichloromethane (“DCM”, 5 mL). To the reaction mixture was added a solution of boron tribromide in methylene chloride (1.6 mL, 1.6 mmol, 1.0 M) at 0° C. The resulting mixture was allowed to warm up to rt and stirred overnight. The resulted mixture was cooled in a dry ice bath when water (10 mL) was added. The mixture was allowed to warm up to rt and EtOAc was added. The aqueous layer was extracted with EtOAc twice. The organic layers were combined and concentrated under vacuum. The crude product was purified by silica gel column chromatography to give the desired product as a light brown powder (34 mg, 20%). LCMS for C19H19BrClN4O (M+H)+: m/z=371.1, 373.1. 1H NMR (400 MHz, DMSO-d6): δ 9.30 (s, 1H), 9.11 (s, 1H), 7.95 (s, 1H), 7.74 (t, J=6.1 Hz, 1H), 7.42 (m, 1H), 7.08 (t, J=7.9 Hz, 1H), 7.03 (dd, J=8.7, 7.6 Hz, 1H), 6.71 (dd, J=11.5, 7.6 Hz, 1H), 6.69 (s, 1H), 6.58 (dd, J=8.0, 2.3 Hz, 1H), 4.56 (m, 2H), 3.50 (m, 2H), 2.56 (t, J=7.1 Hz, 2H).
