Reaction Steps

A mixture of veratraldehyde (200 g, 1.20 mol), ammonium acetate (94.0 g, 1.22 mol) nitroethane (400 ml, 418 g, 5.57 mol) and toluene (200 ml) is refluxed for 2 hours and thirty minutes, with ternary azeotrope toluene/nitro ethane/water being distilled off and formed water being separated. The red solution is cooled down to about 40° C. and is concentrated to residue at 40°-50° C./20 mbar.
