Procedure

A mixture of ethyl propionylacetate (25 g, 0.173 mol) and 3-hydroxypropionitrile (18.48 g, 0.26 mol) was stirred and heated at 200-205° C. for 2 h and the ethanol formed was removed by distillation. The residue was subjected to high vacuum distillation and the fraction distilling at 120-125° C. at 0.4 mm of Hg was collected to get 2-cyanoethyl propionylacetate (21.5 g, 73.4%).
