6-((3-bromo-4,5-dihydroisoxazol-5-yl)methoxy)-3,4-dihydroquinolin-2(1H)-one (0.1 g, 0.308 mmol) and (4-(difluoromethoxy)phenyl)methanamine (0.149 g, 0.923 mmol) were heated at 160° C. for 30 min. The reaction mixture was dissolved in methanol, concentrated, and the crude product purified by preparative HPLC on a Kromasil C4 column (250×20 mm) using a 0-100% gradient of ACN in 0.1% TFA to give 6-((3-(4-(difluoromethoxy)benzylamino)-4,5-dihydroisoxazol-5-yl)methoxy)-3,4-dihydroquinolin-2(1H)-one as a white solid (0.015 g, 23%). 1H NMR 400 MHz, DMSO-d6: δ 2.41 (q, J=7.20 Hz, 2H), 2.78-2.85 (m, 3H), 3.08 (q, J=9.60 Hz, 1H), 3.89-3.97 (m, 2H), 4.18 (d, J=6.00 Hz, 2H), 4.62-4.65 (m, 1H), 6.62 (t, J=6.00 Hz, 1H), 6.72-6.78 (m, 2H), 6.81 (d, J=2.00 Hz, 1H), 7.02-7.39 (m, 5H), 9.91 (s, 1H). LCMS: RT 1.501 min; LCMS (ES-API), m/z 418.2 (M+H).
