2',4'-Dihydroxyacetophenone → HCID 21544793, compound

Participants

Reaction Steps

A solution of resacetophenone (15.2 g), phenylglycidyl ether (15.0 g) and benzyltrimethylammonium hydroxide (5 drops of a 40% solution) in 2-ethoxyethanol (75 ml) was heated under reflux for 2 days. Removal of solvent under reduced pressure yielded a dark, viscous oil, which was allowed to stand for 48 hours, by which time it had crystallized to a solid mass. This was triturated with a mixture of ether and light petroleum (b.p. 40°-60°.), filtered, washed with a little more ether-petroleum and dried. Crystallization from methanol gave 1-(4-acetyl-3-hydroxyphenoxy)-2-hydroxy-3-phenoxypropane as a greyish-white solid, 9.0 g, m.p. 63°-65°.
