실험 절차

A mixture of methyl (1aRS,7bSR)-5-(2-{N—[((R)-1-ethylpyrrolidine-2-yl)carbonyl]-N-methyl-aminomethyl}-4-fluorobenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (Intermediate 155, 0.177 g) and lithium hydroxide monohydrate (0.136 g) in dioxane (5 mL) and water (2 mL) was stirred and heated at 100° C. for 19.5 hours. After cooling, the mixture was evaporated to dryness and the residue was acidified by addition of aqueous citric acid solution (10%). The resultant solid was collected by filtration, washed with water and dried under vacuum at 40° C. The solid was purified by preparative HPLC (C18) eluting with a mixture of methanol and water, containing 0.1% formic acid, with a gradient of 10-98% to give (1aRS,7bSR)-5-(2-{N—[((R)-1-ethylpyrrolidine-2-yl)carbonyl]-N-methylaminomethyl}-4-fluoro-benzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylic acid (0.053 g) as a white solid.
