Reaction Steps

Add acetic acid (2.0 mL) and water (2.0 mL) to di-tert-butyl (1R,2R,3S,4S,5R,6R)-2-(tert-butoxycarbonylamino)-3-[(3,4-dichlorophenyl)methoxy]-4-[(2-methyl-1,2,4-triazol-3-yl)sulfanyl]bicyclo[3.1.0]hexane-2,6-dicarboxylate (0.305 g, 0.445 mmol) in a microwave vessel and seal and heat the mixture to 140° C. for 25 minutes. Cool and concentrate the mixture to dryness, and then add 5 N hydrochloric acid (2 mL), acetonitrile (2 mL), and transfer to a vial. Lyophilize overnight to yield the title compound as a white solid (0.227 g, 0.445 mmol; 95%): MS (m/z): 473/475/477 (M+1).
