Reaction Steps

Potassium tert-butoxide (4.32 g, 0.0385 mol) is added portionwise to a 0° C. solution of ethyl 5-(p-chlorophenyl)-1-hydroxypyrrole-3-carboxylate (9.3 g, 0.035 mol) in anhydrous tetrahydrofuran. Methyl iodide (5.46 g, 0.0385 mol) is then added slowly to the solution at room temperature. The reaction mixture is stirred for 3 hours, diluted with water and extracted with ether. The combined ether extracts are washed sequentially with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give a solid. Crystallization from hexanes gives the title compound as a white crystalline solid (9.25 g, 94%), mp 65°-66° C.
