Versuchsvorschrift

To a stirred solution of 5-(4-chlorophenyl)-N-methoxy-N,1,4-trimethyl-3-(4-sulfamoylphenyl)-1H-pyrrole-2-carboxamide (compound 49φ, 0.650 g, 1.45 mmol) in ethyl acetate (12 ml) was added DMF (0.65 ml) and DMF acetal (0.207 g, 0.233 ml, 1.74 mmol) sequentially at room temperature. The reaction mixture was then stirred at room temperature for 15 hr under a nitrogen atmosphere. The progress of the reaction was monitored by TLC. The precipitated out product was filtered and washed with ether (10 ml) to obtain the title compound (0.600 g, 82.19%).
