Procedure

12.5 Grams of cinnamyl chloride and 21 g of 2-methylaminoethanol were dissolved in 100 ml of ethanol, and the solution was refluxed for 5 hours. The solvent was removed by evaporation, to the residue thus obtained was added water and washed with n-hexane. To the water layer was added 3N-sodium hydroxide aqueous solution to adjust its pH to 10-11, and extracted with ether. The ether extract was washed with water and dried with anhydrous sodium sulfate, and the solvent was removed by evaporation. The residue was purified by means of a silica gel column chromatography (eluent: chloroform: methanol=25:1) to yield 15 g of 2-[N-methyl-N-(3-phenyl-2(E)-propenyl)amino]ethanol.
