Participants

Reaction Steps

A mixture of 70.3 g. (0.284 mole) 4'-(2-methyl-2-dioxolanyl) pivalophenone and 700 ml of 2N hydrochloric acid is refluxed for 18 hours. The resulting solution is cooled, extracted with ether, the ether washed with salt water, dried, evaporated and the resulting residue is distilled at 88°-86° C mm Hg to give 4'-acetylpivalophenone.
