Versuchsvorschrift

2-(1-Ethylpiperidine-4-ylmethyl)-4-fluorobenzenesulfonyl chloride (Intermediate 178, 0.165 g) was added to a solution of methyl (1aRS,7bSR)-5-amino-1,1a,2,7b-tetrahydrocyclopropa-[c]chromene-4-carboxylate (Intermediate 42, 0.290 g) in DCM (5 mL) and pyridine (1 mL) and the resultant mixture was stirred at room temperature for 21 hours. The mixture was evaporated to dryness and the residue was purified by chromatography on silica eluting with a mixture of 2M NH3 in methanol and DCM with a gradient of 0-20% to give methyl (1aRS,7bSR)-5-[2-(1-ethyl-piperidin-4-ylmethyl)-4-fluorobenzenesulfonylamino]-1,1a,2,7b-tetrahydrocyclopropa-[c]chromene-4-carboxylate (0.200 g) as a solid.
