Participants

Reaction Steps

To a solution of bis(2-methoxyethyl)aminosulfur trifluoride (11 ml, 61 mmol) in dichloromethane (200 ml), a solution of the above 1-(4-chloro-2-methylphenyl)-5-(2-hydroxyethyl)-2-methyl-N-[4-(methylsulfonyl)phenyl]-1H-pyrrole-3-carboxamide (6.8 g, 15 mmol) in dichloromethane (200 ml) was added, and the mixture was stirred at room temperature for 3 hours. The reaction mixture was poured to a saturated aqueous sodium hydrogencarbonate solution cooled to 0° C., and the mixture was stirred at room temperature for 15 minutes. The organic layer was washed with saturated brine, and after it was dried with magnesium sulfate, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane-hexane:ethyl acetate=4:1) to give the title compound (3.8 g, 56%) as a solid.
