Abstract
The invention comprises a -methyl-a -phenyl-succinodinitrile, and a process for the preparation of N-methyl-a -phenyl-a -methyl-succinimide by reacting an ester of a -cyano-b -methylcinnamic acid with at least one molecular equivalent of an alkali cyanide for each molecular equivalent of said ester at a temperature above 70 DEG C., heating the a -methyl-a -phenyl-succinodinitrile so obtained with methylamine in the presence of water in a closed vessel at a temperature between 110 DEG and 200 DEG C., and heating the resultant reaction product, e.g. at a temperature between 110 DEG and 250 DEG C. at atmospheric pressure. The alkali cyanide may be employed in approximately 10 to 20 per cent excess, preferably in a water-miscible organic solvent containing 5 to 50 per cent water. The methylamine may be employed in a quantity of 2 to 3 molecular equivalents per molecular equivalent of a - methyl - a - phenyl - succinodinitrile at a temperature between 115 DEG and 150 DEG C. Suitable water-miscible organic solvents are lower aliphatic alcohols such as methanol, ethanol, isopropanol, n-propanol or n-butanol. Detailed examples are given.
