Versuchsvorschrift

A solution of potassium carbonate (0.345 g) in water (2 mL) was added to a solution of methyl (1aRS,7bSR)-5-(4-fluoro-2-[N-methyl-N-(2,2,2-trifluoroacetyl)-aminomethyl]-benzenesulfonyl-amino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (Intermediate 157, 0.257 g) in methanol (12 mL) and the mixture was heated at 45° C. for 3 hours. After cooling, the volatiles were removed in vacuo and the residue was treated with water (30 mL) and saturated with sodium chloride and extracted with ethyl acetate (50 mL). The organic layer was dried (Na2SO4) and filtered and the filtrate was evaporated to dryness to give methyl (1aRS,7bSR)-5-(4-fluoro-2-methylaminomethylbenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylate (0.156 g) as a solid.
