実験手順

A solution of methyl 5-amino-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (Intermediate 42, 0.19 g) in DCM (10 mL) and pyridine (3.5 mL) was treated with a solution of 2-((S)-1-ethylpyrrolidin-3-ylmethyl)-4-fluorobenzenesulfonyl chloride (Intermediate 114, 0.26 g) in DCM (5 mL) and the mixture was stirred and heated at 40° C. for 1 hour. The resultant mixture was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of DCM and methanol with a gradient of 0-25%, then flushed with 100% methanol to give methyl (1aS,7bR)-5-[2-((S)-1-ethylpyrrolidin-3-ylmethyl)-4-fluoro-benzenesulfonylamino]-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (0.107 g) as a gum.
