Versuchsvorschrift

[2-(2-Chlorobenzoyl)-1H-pyrrol-1-yl]-carbamic acid, ethyl ester (22 g, 75.1 mmol), sodium carbonate (16.0 g, 0.112 mol) and methyl iodide (13 g, 0.122 mol) were added to 100 ml of dry DMF and the mixture stirred at ambient temperature for 78 hours. The reaction was quenched with 1 liter of H2O and extracted with five 200 ml portions of diethyl ether. The combined extracts were washed with water and brine, dried (MgSO4), filtered, and evaporated to give 15 g of solid. This solid was purified by HPLC (silica gel, DCM) to give 13.1 g (57%) of crystals, m.p. 54°-56°.
