Reaction Steps
(1R*,5R*,6R*)-1-amino-6-phenyl-3-oxa-bicyclo[3.1.0]hexan-2-one (0.14 g, 0.74 mmol) was dissolved in 3 mL of pyridine. After cooling to 0° C., 5-(5-trifluoromethyl-isoxazol-3-yl)-thiophene-2-sulfonyl chloride (0.31 g, 0.96 mmol) was added in one portion. The reaction mixture was warmed to room temperature and stirred overnight. After concentration, the reaction mixture was diluted with EtOAc, washed with 10% citric acid, water (×2), 5% NaHCO3 and brine and dried over Na2SO4. After concentration, the crude product was purified by column chromatography using 2:1 hexanes/EtOAc to afford 0.26 g (75%) of the desired product.
