Abstract

A method of preparing a 4-substituted 1 (7 "-alkoxy-3", 7 "-dimethyloctanyloxy) benzene compound corresponding to the formula: formula wherein r represents a straight chain lower alkyl radical of 1 to 4 carbon atoms and x represents methyl, ethyl, N-propyl, isopropyl, methoxy, ethoxy, aceto or 3,4-methylenedioxy consisting of: a: reacting citronellol with hydrobromic acid gas at a temperature between 50 and 150ºC approximately, to produce 1,7-dibromo-3,7-dimethyloctane; b. Reacting the product 1,7-dibromo-3,7-dimethyloctane with a substituted phenol of the formula formula wherein x is as defined above, in the presence of an organic reaction medium and an alkali metal hydroxide, a temperature between the environment and about 150º c, after slow distillation of the mixture to produce the dehydrobromination or allowing the dehydrobromination to occur spontaneously in the reaction conditions of this stage itself. C. React the product thus obtained with a lower alkanol of formula r-oh, where r is as defined above, in the presence of an acid, around room temperature and recover the product 1- (7 "-alkoxy-3 "7, 7" -dimethyloctanyloxy) 4-substituted benzene.
