Reaction Steps

A mixture of 20.0 g (90 mmole) 4-n-propylbenzaldehyde diethylacetal, 20.4 g (180 mmole) ethyl cyanoacetate, 7.2 g (93.4 mmole) ammonium acetate and 60 ml toluene are heated at reflux for six hours, cooled and poured into water. The resulting mixture was extracted with ethyl ether, dried (MgSO4) and the volatiles evaporated in vacuo to afford 23.0 g crude yellow oil which was purified by chromatography on a silica gel column, eluting with 2:1 methylene chloride/hexane to give 20.58 g (94%) of the desired product.
