실험 절차

4-Dimethylaminobutylamine (0.348 g) and triethylamine (0.2 ml) were added to a suspension of cis-(3aRS,9bRS)-7-(2-fluorobenzenesulfonylamino)-1,3a,4,9b-tetrahydro-2H-furo[2,3-c]chromene-6-carboxylic acid (Intermediate 57, 0.15 g) in acetonitrile (1.5 mL) and the mixture was heated at 130° C. in a sealed tube for 36 hours. The mixture was then diluted with water (2 mL) and the solution was purified by preparative HPLC (C6-phenyl) eluting with a mixture of methanol and water, containing 0.1% formic acid, with a gradient of 5-98%. The isolated product was further purified by chromatography on silica eluting with a mixture of methanol and DCM with a gradient of 0-15% to give cis-(3aRS,9bRS)-7-[2-(4-dimethylaminobutylamino)-benzenesulfonylamino]-1,3a,4,9b-tetrahydro-2H-furo[2,3-c]chromene-6-carboxylic acid (0.062 g) as a glass foam.
