Versuchsvorschrift

{2-[5-(4-Chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl]pyridin-5-yl}amine [prepared by the method described in Example 5, but substituting the methyl ester of zomepirac for the methyl ester of tolmetin in Step (a)] (0.45 g, 1.32 mmol) and dimethylcarbamoyl chloride (0.13 ml, 1.46 mmol) were dissolved in pyridine (6.6 ml), and the mixture was stirred at room temperature for 96 h. The solvents were removed in vacuo and the residue was crystallized from chloroform-hexane mixture to give 1-{2-[5-(4-chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl]pyridin-5-yl }-3,3-dimethylurea (0.31 g, 57%) as a solid, mp 227.2-230.0° C.
