A solution of 4.00 g (0.0292 m) of ethyl N,2-dicyanoacetimidate and 2.86 g (0.0292 m) 2-methylpiperidine in 80 ml of tetrahydrofuran is stirred for five days at room temperature. The reaction product is isolated in the same way as 3-(cyanoimino)-3-(N,N-diethylamino)propionitrile to give 0.76 g of product, 14%. This product is further purified by chromatography on a Merck "B" column to give material whose nmr, ir, and mass spec are consistent with the desired product.
