Procedure

10.60 g of (chloromethylene)dimethylammonium chloride and 6.25 g of N-(triisopropylsilyl)-pyrrole are suspended in 200 ml of CH2Cl2 under nitrogen at 0-5° C. The suspension is warmed to 60° C. and stirred for 30 minutes. Afterwards the mixture is cooled to ambient temperature. The suspension is filtered and washed with diethylether to give 5.67 g of the title compound as grey solid.
