Procedure

To N-(1-benzyl-4-piperidinyl)-2-formyl-3-methylaniline (7.0 g) are added methanol (100 ml) and methyl (triphenylphosphoranylidene)acetate (15 g) and the mixture is refluxed for 1 hour. After cooling, the formed crystals are separated by filtration to give methyl 2-methyl-5-[(1-benzyl-4-piperidinyl)amino]cinnamate (5.6 g) as pale yellow powders, m.p. 140°-142° C.
