Reaction Steps
4-{5-(4-Chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl}aniline (0.33 g, 0.98 mmol) and 1,1'-carbonyldiimidazole (0.4 g, 2.46 mmol) were dissolved in DMF, and the reaction mixture was stirred at room temperature for 1 h. Ethanolamine (0.3 ml, 4.91 mmol) was added and after 1.5 h the mixture was diluted with water. The product was extracted into ethyl acetate, and the organic layer was dried over MgSO4 and then concentrated under vacuum. Purification by flash chromatography (ethyl acetate), followed by recrystallization from hexane-chloroform gave 1-{4-[5-(4-chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl]phenyl}-3-(2-hydroxyethyl)urea (239 mg, 57%) as a solid, mp 209.6-210.2° C.
