Procedure

Dehydration by distillation from a few drops of 20% aqueous sulfuric acid gives a mixture of 5-(1,2-dimethyldec-1-enyl)resorcinol dimethyl ether and 5-(1-methylenyl-2-methyldecyl)resorcinol dimethyl ether which is hydrogenated over 10% palladium-on-carbon in absolute ethanol at 50 p.s.i. and 25° to give 5-(1,2-dimethyldecyl)-resorcinol dimethyl ether.
