Procedure

To a solution of 2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-9-(1-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-1H-imidazol-4-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (250 mg, 0.51 mmol) in EtOH (15 mL) was added a solution of hydrogen chloride in dioxane (1.28 mL, 5.1 mmol). The mixture was refluxed for 2 h, cooled to room temperature and concentrated. The resulting precipitates were washed with EtOAc to give 207 as a yellow solid (115.2 mg, yield 56%). 1H NMR (Methane-d4, 400 MHz): δ9.12 (d, J=1.2 Hz, 1H), 8.78 (s, 1H), 8.65 (d, J=8.4 Hz, 1H), 8.28 (s, 1H), 8.17 (d, J=1.2 Hz, 1H), 7.58-7.53 (m, 2H), 5.85-5.78 (m, 1H), 4.71-4.63 (m, 4H), 4.41 (t, J=5.2 Hz, 2H), 3.96 (t, J=5.2 Hz, 2H), 1.66 (d, J=6.8 Hz, 6H). MS: (ESI, m/z)=406 [M+H]+
