Versuchsvorschrift

A mixture of methyl 7-amino-2,3-dihydro-1H-pyrrolo[1,2-a]indole-8-carboxylate (Intermediate 18, 0.300 g) and 2-bromo-4-fluorobenzenesulfonyl chloride (0.427 g) in pyridine (4 mL) and DCM (12 mL) was stirred at room temperature for 30 minutes. The resultant mixture was diluted with ethyl acetate and washed with aqueous potassium carbonate solution (10%) and brine. The organic layer was dried (MgSO4), filtered and the filtrate was concentrated in vacuo. The residue was purified by chromatography on silica, eluting with a mixture of methanol and DCM with a gradient of 0-2% to give methyl 7-(2-bromo-4-fluorobenzenesulfonylamino]-2,3-dihydro-1H-pyrrolo[1,2-a]indole-8-carboxylate (0.350 g) as a white foam.
