실험 절차
A mixture of methyl (1aRS,7bSR)-5-(2-aminomethyl-4-fluorobenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (Intermediate 102, 0.515 g), HATU (0.483 g), (S)—N-ethylpyrrolidine-2-carboxylic acid (Intermediate 106, 0.182 g) and N,N-di-isopropyl-N-ethylamine (0.328 g) in dry DMF (25 mL) was stirred at room temperature for 2 hours. The mixture was concentrated under vacuum and the residue was diluted with water and extracted with ethyl acetate, washed with water, dried (MgSO4) and filtered. The filtrate was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of methanol and DCM, with a gradient of 1-2% to give methyl (1aRS,7bSR)-5-{2-[((S)-1-ethylpyrrolidin-2-yl)cabonyl-aminomethyl]-4-fluorobenzenesulfonylamino}-1,1a,2,7b-tetrahydrocyclopropa-[c]chromene-4-carboxylate (0.505 g) as a glassy solid.
