実験手順

Methyl (1aRS,7bSR)-5-(2-{[((S)-1-ethylpyrrolidine-3-carbonyl)amino]methyl}-4-fluoro-benzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (Intermediate 188, 0.190 g) and lithium hydroxide monohydrate (0.150 g) were suspended in dioxane (5 mL) and water (5 mL) and the mixture was stirred and heated at 100° C. for 18.5 hours. After cooling, the volatiles were removed in vacuo and the residue was acidified by addition of aqueous citric acid solution (10%) and extracted with DCM. The organic layer was dried (Na2SO4) and filtered. The filtrate was evaporated to dryness and the residue was purified by preparative HPLC (C18) eluting with a mixture of acetonitrile and water, containing 0.1% formic acid, with a gradient of 25-60% to give (1aRS,7bSR)-5-(2-{[((S)-1-ethylpyrrolidine-3-carbonyl)amino]methyl}-4-fluorobenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylic acid (0.092 g) as a white solid.
