experimental part, p. 2874 - 2878 (2009/04/06)

An efficient preparation of (Z)-2-[quinazolin-4(3H)-ylidene]acetonitriles has been achieved in one pot by addition of 2-lithioacetonitrile to the cyano carbon of N-(2-cyanophenyl)alkanimidates, followed by intramolecular attack of the resulting imino anio
