Reaction Steps

20.0 g of trans-2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-3-methyl-5-(E)-propenylbenzofurane and 13.6 g of 3-allyl-1,3-oxazolidine are held in 240 ml of absolute alcohol for 48 hours at 70° C. and subsequently the solvent and excess 3-allyl-1,3-oxazolidine are removed in vacuum. After purification by means of a chromatographic column there is obtained 14.4 g of N-(5-(trans-2,3-dihydro-7-methoxy-3-methyl-5-(E)-propenyl-benzofuran-2-yl)-2-hydroxy-3-methoxyphenyl-methyl)-N-(2-hydroxyethyl)-N-allylamine, a colourless oil.
