A solution of methyl 4-(2-carbamoyl-9-fluoro-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-10-yl)-2-hydroxy-2-methylbut-3-ynoate (120 mg, 0.32 mmol, 1.00 equiv) and cyclopropanamine (1.83 g, 32.05 mmol, 99.72 equiv) in methanol (2 mL) was stirred for 12 h at 40° C. The resulting mixture was concentrated under vacuum and the residue was applied onto a silica gel column with dichloromethane/methanol (30:1) to give the titled compound, 23 mg (18%), as a yellow solid.
