الإجراء التجريبي

Methyl 2-(aminosulfonyl)-1-methyl-1H-pyrrole-3-carboxylate (0.10 g, 0.46 mmol) and 0.13 g (0.50 mmol) of phenyl (4-methoxy-6-methyl-1,3,5-triazin-2-yl)carbamate were combined in 2 mL of acetonitrile and 0.075 mL of DBU was added and the resulting amber solution was stirred at ambient temperature for 30 min. The reaction mixture was diluted with 15 mL of water and acidified with 0.5 mL 1N HCl and the resulting precipitate was collected by filtration and rinsed successively with water and ether, then dried to afford 0.13 g oil the title compound as a white solid, m.p. 189°-190° C. (dec).
