A solution containing 15.4 g. of l-hydroxy-2,6-dimethoxybenzene and 14.4 g. of 1,1-dimethyl-1-hydroxyheptane in 20 mL. of methane-sulfonic acid was heated at 50° C. and stirred for three and one-half hours. The reaction mixture next was poured over 50 g. of ice, and the resulting aqueous solution was extracted several times with dichloromethane. The organic extracts were combined, washed with water and with saturated aqueous sodium bicarbonate solution, and dried. Removal of the solvent by evaporation under reduced pressure provided 27.4 g. of l-hydroxy-2,6-dimethoxy-4-(l,1-dimethyl-heptyl)benzene as an oil. Source Dominianni 1978... 

In a similar way, 2,3-dimethoxybenzaldehyde with HO-protected 6-chlorohexan-1-ol and lithium afforded after acidic treatment 1,2-dimethoxy-3-(7-hydroxy-heptyl)benzene. Demethylation and bromide formation with boron tribromide gave 1,2-dihydroxy-3-(7-bromohepty0benzene which interacted with lithium-1-octyne in tetrahydrofuran containing hexamethylphosphoric triamide to give after selective catalytic hydrogenation, (15 1)-urushiol (ref. 138). In a different approach this has been synthesised in moderate yield from 2,3-dimethoxyphenyllithium and 1,7-dibromheptane as shown in the following scheme (ref. 139)...
