Procedure

A solution of 2-bromo-4-fluorobenzonitrile (200 mg, 1.00 mmol), DL-α-amino-ε-caprolactam hydrochloride (173 mg, 1.05 mmol) and DIEA (0.620 mL, 3.56 mmol) in DMSO (3 mL) was stirred at 120 C for 18 h. Water and EtOAc were added. The solid found between the bi-layer was collected by filtration to give 2-bromo-4-(2-oxoazepan-3-ylamino)benzonitrile (155 mg)
