Procedure

A solution 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 (150 mg, 0.40 mmol, 1.00 equiv), azetidine-3-carbonitrile hydrochloride (237 mg, 2.00 mmol, 5.00 equiv), triethylamine (203 mg, 2.01 mmol, 5.00 equiv) in methanol (5 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 8.8 mg (5%) the titled compound as an off-white solid.
