実験手順

25.7 g of ethyl 4-bromomethylphenylacetate and 28 g of hexamethylenetetramine are dissolved in 200 ml of 20% acetic acid, heated to 100° C. with stirring and stirred for four hours. The reaction solution is allowed to cool and sufficient sodium carbonate is added until a saturated solution is obtained. This solution is extracted with ether, dried and the ether is then removed. The residue is purified by chromatography (silica gel/methyl t-butyl ether/ether 1:1).
