---|---|---|
With toluene-4-sulfonic acid; In toluene; | A mixture of 12.6 g of 4-ethylcyclohexanone, 17.0 g of <strong>[6296-99-7]diethyl aminomethylenemalonate</strong>, and 950 mg of p-toluenesulfonic acid in 170 ml of toluene is heated at reflux for 48 hours with a water separator, under nitrogen atmosphere. The solvent is removed under nitrogen atmosphere and under vacuum, and the residue purified by flash column chromatography on a silica gel column eluted with methylene chloride. The desired product, diethyl N-(4-ethylcyclohexen-1-yl)-aminomethylenemalonate is obtained as an oil. | |
