To a solution of 10-(2-fluoropyridin-3-yl)-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (0.047 g, 0.12 mmol) in DME (2 mL) was added 10% aq HCl (2 mL). The reaction mixture was allowed to stir and heat at 80° C. for 18 hours before cooling and concentrating under reduced pressure. The crude material was dissolved in DMF and purified by reverse phase HPLC to provide 203 (25 mg, 55%). 1H NMR (400 MHz, DMSO) δ 11.82 (s, 1H), 8.88 (d, J=2.3, 1H), 7.92 (d, J=6.7, 2H), 7.67 (ddd, J=9.0, 7.7, 2.2, 2H), 7.38 (d, J=4.8, 1H), 7.07 (d, J=8.6, 1H), 6.31 (t, J=6.7, 1H), 5.81 (dt, J=13.2, 6.6, 1H), 4.54 (q, J=5.8, 4H), 1.48 (d, J=6.6, 6H). MS(ESI(+)): m/z 389.1 (M+H)
