Participants

Reaction Steps

7.7 g (50 millimoles) of 3-methoxymethoxy-phenol and 110 g of 50% sulfuric acid are dissolved in 150 g of chloroform, whereupon 6.8 g of isoprene are added at 60° C. within 20 minutes. The reaction mixture is allowed to stated at 60° C. for 3 hours, separated, the organic phase is evaporated and the residue is heated to boiling in the presence of 2.5 g of dichloro-dicyano-benzoquinone in 100 ml of dioxane for 10 hours. Then one proceeds as described in Example 8. Thus 7.6 g of the desired compound are obtained in the form of a light yellow oil, yield 69%.
