Participants

Reaction Steps

A suspension of 237.0 g. (1.38 mole) of pyrrolidine perchlorate in 500 ml. of benzene and 500 ml. of ethyl acetate is stirred and refluxed with water separation for 1 hr., then cooled to room temperature. 131.2 g. (1.38 mole) pyrrole-2-carboxaldehyde is added and the reaction mixture is stirred and refluxed with water separation for 6 hrs. After the whole has been cooled in an ice bath, the solvent is decanted from the solid product, and the product is recrystalllized from 1:1 acetonitrile/ether to give 1-(pyrrol- 2-ylmethylene)-pyrrolidinium perchlorate as a yellow solid; m.p. 100°-102° C.
