A solution of (S)-perhydro-azepine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide hydrochloride (prepared according to Method T, step 6) (0.60 g, 4.20 mmol), 1-Bromo-4-chloro-benzene (0.80 g, 4.20 mmol), potassium carbonate (0.87 g, 6.29 mmol) and copper (I) iodide (0.08 g, 0.42 mmol) in DMA (10.0 mL), is heated at 100° C. in a sealed tube for 48 hours. The reaction mixture is diluted with EtOAc and washed with water. The water phase is acidified with 1N HCl and then extracted with EtOAc. The organic layers are combined, and after drying over anhydrous Na2SO4, removal of the solvent affords the title product that is used in the next step without any further purification. m/z 254 [M+H].
