To a solution of 7-(4-(trifluoromethoxy)phenyl)-3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one (660 mgs, 2.0 mmol) in THF (6 mL), 1.0M Borane in THF (6.0 mL, 6.0 mmol) was added and the mixture was heated at 70° C. After 16 h, the mixture was cooled to rt and Methanol (22 mL) and 6.0M HCl (22 mL) was added and stirred at rt for 2 h. The reaction mixture was then concentrated and the solids formed were filtered and washed with ether and dried to give 7-(4-(trifluoromethoxy)phenyl)-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine as HCl salt. The above compound (100 mgs, 0.29 mmol), pyrimidine-2-carboxylic acid (47 mgs, 0.38 mmol), HATU (143 mgs, 0.38 mmol), in DMF (1 mL) was added NMM (0.1 mL, 0.86 mmol) and stirred at 60° C. for 30 min. The reaction mixture was then diluted with EtOAc and washed with NaHCO3, brine and dried (MgS(O)4). The mixture was the filtered, concentrated and chromatographed (SiO2, 50% EtOAc/DCM) to provide the title compound.
