Versuchsvorschrift

To a solution of methyl 2-[(4′-methoxy[1,1′-biphenyl]-4-yl)sulfonyl]amino-4,5-epoxypentanoate 1d (0.7 g, 1.79 mmol) in benzene (5 mL) and Et3N (0.33 mL, 2.3 mmol) at room temperature is added slowly 2-mercaptothiazole (0.52 g, 4.48 mmol). The reaction mixture is stirred for 4 h at room temperature. The resulting mixture is diluted with water, and the mixture is then extracted three times with EtOAc. The combined EtOAc layer is consecutively washed with water, and brine, dried over MgSO4 and concentrated to an oil under reduced pressure. Purification is accomplished by column chromatography with hexane/EtOAc (4:1 to 7:3 to 6:4) eluent to give the desired product.
