Reaction Conditions

Reaction Steps

To a suspension of 12.0 g (107 mmol) of potassium tert-butoxide at 60% in oil, in 100 ml of anhydrous tetrahydrofuran, is added dropwise a mixture of 13.3 g (71.1 mmol) of methyl (E)-3-(3-cyanophenyl)acrylate (CAS 193151-10-9) and 13.9 g (71.1 mmol) of tosylmethyl isocyanide (CAS 36635-61-7) dissolved in 100 ml of tetrahydrofuran, while maintaining the temperature of the reaction medium at about 25° C. The mixture is then stirred for 2 hours at room temperature, and is then partially concentrated under reduced pressure. This solution is then poured into ice-water and the reaction product is then extracted with dichloromethane. The organic phase is dried over sodium sulfate and the solvent is evaporated off under reduced pressure to give a brown solid, which is triturated in chloroform to give 10.8 g of methyl 4-(3-cyanophenyl)-1H-pyrrole-3-carboxylate in the form of a beige-coloured solid after cooling, filtering off and drying.
