Versuchsvorschrift
Bromine (0.35 g, 0.11 ml, 2.2 mmol) was added drop wise to a stirred suspension of methyl 3-(4-(N-(tert-butyl)sulfamoyl)-3-methylphenyl)-4-methylthiophene-2-carboxylate (41a, 0.70 g, 1.83 mmol) in DCM (15 ml) at 0° C. The reaction mixture was then stirred at 25° C. for 3 hours. The progress of the reaction was monitored by TLC. The reaction mixture was then concentrated. DCM (50 ml) was added to the residue. The mixture so obtained was washed with water (2×20 ml), brine (lx 20 ml) and dried over sodium sulfate. The dried organic layer was then concentrated under reduced pressure to obtain a crude product as semi-solid (0.7 g), which was then purified by flash column chromatography using 40% ethyl acetate in hexanes as an eluent to obtain the title compound (0.63 g, 85.13%).
