3N was not used). After leaving to warm to r.t. over a period of 3-4 h, the reaction mixture was gently heated to reflux for 16 h, except when TLC analysis already showed complete disappearance of the starting amide (see Table 1). The solvent was then evaporated under reduced pressure and the resulting nitrile was purified by column chromatography on silica gel.
