Hydrochloric Acid → HCID 70359885, compound

Participants

Reaction Steps

A mixture of 4.0 g. (9.56 mmoles) of trans-3-[4-(1,1-dimethylheptyl)-2-hydroxyphenyl]-4-(3-hydroxypropyl)cyclohexanone ethylene ketal, 50 ml. of 2N hydrochloric acid and 100 ml. of tetrahydrofuran was heated at reflux for 2 hours. The reaction was cooled and added to 500 ml. saturated sodium chloride and 250 ml. ether. The ether extract was separated and washed once with 500 ml. saturated sodium chloride, once with 500 ml. saturated sodium bicarbonate, dried over magnesium sulfate and evaporated (aspirator) to an oil. The crude oil was purified via column chromatography on 200 g. of silica gel eluted with 80% ether-hexane to yield 2.93 g. (82%) of the title compound as an oil.
