Reaction Steps

A solution of 9-fluoro-10-(3-hydroxy-3-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-2-yl)but-1-yn-1-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide (200 mg, 0.39 mmol, 1.00 equiv) and TFA (1.5 mL) in dichloromethane (4.5 mL) was stirred for 5 h at room temperature. The resulting solution was diluted with 50 mL of dichloromethane. The pH value of the solution was adjusted to 9 with saturated potassium carbonate. The resulting mixture was washed with water, dried over sodium sulfate, and concentrated under vacuum. The residue was applied onto a silica gel column with DCM/MeOH (10/1) to give the titled compound as an off-white solid.
