실험 절차

A mixture of (1aRS,7bSR)-5-(2-fluorobenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa-[c]chromene-4-carboxylic acid (Intermediate 67, 0.15 g), 3-dimethylaminopropylamine (1.26 g) and triethylamine (0.62 g) in NMP (6 mL) was stirred and heated at 140° C. for 48 hours. After cooling, the mixture was concentrated under vacuum and the residue was purified by chromatography on silica, eluting with a mixture of methanol and DCM with a gradient of 5-10%. The resultant product was repurified by preparative TLC, eluting with a mixture of methanol and DCM (10%) to give (1aRS,7bSR)-5-[2-(3-dimethylaminopropylamino)-benzenesulfonylamino]-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylic acid (0.08 g) as an off white solid.
