Procedure

A solution of 7-(4-(trifluoromethyl)phenyl)-3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one (3.6 g, 11.7 mmol) and phosphorous pentachloride (2.56 g, 12.3 mmol) in toluene (80 mL) was refluxed for 2 hours. The reaction mixture was concentrated to yield 5-chloro-7-(4-(trifluoromethyl)phenyl)-2,3-dihydrobenzo[f][1,4]oxazepine and used in subsequent steps without further purification.
