실험 절차

A mixture of 1-(3-bromo-phenyl)-2-[5-propionyl-1-(2,2,2-trifluoro-ethyl)-1H-pyrrole-3-yl]-ethane-1,2-dione (4.5 g, 0.0108 mol), methylguanidine (2.36 g, 0.0216 mol) and sodium carbonate (2.28 g, 0.0216 mol) in 100 ml ethanol is heated to reflux for three hours. The solvent is evaporated to dryness and the residue is flash chromatographed on silica gel with eluent EtOAc/Ethanol (containing 2 mol ammonia) to afford the product 3.8 gram (75%) as an off-white solid, mp 100-102° C., MS (+) ES 471 [M+H]+.
