実験手順
To a solution of 551 mg of 3-(R)-amino-1-benzyloxy-1,3,4,7-tetrahydro-azepin-2-one from example 1 Step D in 4 mL of dichloromethane and 4 mL of pyridine was added 565 mg of 4-fluorophenyl sulfonyl chloride. The reaction was stirred at room temperature for 24 hours, and an additional 495 mg of the sulfonyl chloride was added. The reaction was stirred for an additional 24 hours, and then the reaction was extracted with ethyl acetate. The mixture was washed with 5% HCl(aq.), NaHCO3(aq.), and NaCl(aq.) solutions. The aqueous layers were re-extracted with ethyl acetate, and the organic layers combined and dried over Na2SO4(s). Filtration and solvent removal gave a light brown solid. Dilution with ethyl ether, filtration, washing of the solids with ethyl ether and drying gave 548 mg of a light brown solid. MS: 391 (M+H).
