Hydrochloric Acid → HCID 19863826, compound

Participants

Reaction Steps

A solution of 4-(3,7,11,15-tetramethyl-2-hexadecenyl)-1,3-benzenediol (870 mg; 2.24 mmole) and conc. hydrochloric acid (2.0 ml) in methanol (15 ml) was heated under reflux for 4 hours, then the reaction solution was poured into 70 ml of water and was extracted twice with isopropyl ether (50 ml). The extract was washed with 100 ml of water (twice) and 100 ml of saturated aqueous solution of sodium chloride (once), followed by drying it over anhydrous magnesium sulfate, distilling off the solvent and subjecting the resultant residue to silica gel column chromatography to thus obtain 610 mg of the title compound from the fractions eluted with hexane-ethyl acetate (10:1). Yield=70%.
