実験手順

Di-tert-butyl (1S,2R,3S,4R,5R,6R)-2-(tert-butoxycarbonylamino)-3-[(4-fluoro-3-methyl-phenyl)sulfanylmethyl]-4-hydroxy-bicyclo[3.1.0]hexane-2,6-dicarboxylate (4.6 g, 8.10 mmol) in pyridine (60 mL) is cooled to 0° C. To this mixture is added methanesulfonyl chloride (1.88 ml, 24.31 mmol). The mixture is warmed to 40° C. and stirred for 1 hour, and cooled to ambient temperature and allowed to stir for 18 hours. The mixture is concentrated under reduced pressure to give a residue. The residue is partitioned between ethyl acetate and 1N aqueous HCl (2×50 mL). The organic layer is separated, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to give the title compound (5.2 g, 8.05 mmol, 99.4% yield): MS (m/z): 643.6 (M−H).
