Reaction Steps

A mixture of 150 g. (2 mole) of nitroethane, 105 g. (0.5 mole) of ethyl-p-chlorocinnamate and 6.6 g. of Triton B (a 35% solution of trimethyl-benzyl-ammonium hydroxide in methanol) is heated for 20 hours at 80°C. After the reaction has finished, toluene is added, washing is carried out with a saturated solution of sodium chloride and the organic solution is dried and evaporated to dryness and the residue is distilled. Yield: 80%; B.P.: 150°-155°C./0.3 mm.Hg.
