실험 절차
A solution of (1aRS,7bSR)-5-(4-fluoro-2-vinylbenzenesulfonylamino)-1,1a,2,7b-tetrahydro-cyclopropa[c]chromene-4-carboxylic acid (Intermediate 74, 0.150 g) and (R)-1-ethylpyrrolidin-3-ylamine (Intermediate 193, 0.25 g) in ethylene glycol (1 ml) was irradiated in the microwave at 200° C. for 30 minutes. After cooling, the mixture was diluted with water and loaded onto a SCX-2 SPE cartridge then washed with water, methanol and 2M ammonia in methanol. The basic fractions were combined and evaporated to dryness. The residue was purified by preparative HPLC (C18) eluting with a mixture of methanol and water, containing 0.1% ammonia, with a gradient of 10-98%. Then further purified by preparative HPLC (C18) eluting with a mixture of acetonitrile and water, containing 0.1% formic acid, with a gradient of 10-60% to give (1aRS,7bSR)-5-{2-[2-((R)-1-ethylpyrrolidin-3-ylamino)ethyl]-4-fluorobenzenesulfonylamino}-1,1a,2,7b-tetrahydro-cyclopropa[c]chromene-4-carboxylic acid (0.005 g) as a white solid.
