Reaction Steps

A Solution of EtOAc/HCl (20 mL) was added to 1-(2-chlorophenyl)-5-(9-(4-chlorophenyl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-2-yl)-1H-1,2,4-triazol-3-ylcarbamic acid (270 mg, 0.6 mmol) in EtOAc (10 mL) in Portions. The resulting mixture was stirred at 50° C. for 5 h. The reaction mixture was filtered and the solid was collected to give 570 (100 mg, 34%). 1H NMR (DMSO, 400 MHz) δ 7.73-7.69 (m, 5H), 7.63-7.61 (m, 2H), 7.55-7.52 (m, 1H), 7.48 (dd, J=2.0, 6.8 Hz, 2H), 7.28-7.25 (m, 2H), 4.80-4.30 (b, 2H), 4.45 (s, 4H). LCMS (ESI) m/z 489.1 (M+H+)
