Participants

Reaction Steps

0.25 Gm. of 2-(5-hydroxy-5H-dibenzo[a,d]cyclohepten-2-yl)propionic acid is stirred in 20 ml. of acetonitrile containing 2.0 gm. of activated manganese dioxide for 12 hours. The solution is then filtered and the filtrate evaporated to afford a 50% yield of 2-(5H-dibenzo[a,d]cyclohepten-5-on-2-yl)propionic acid, m.p. (chloroform-hexane) 138°-139° C.; m.p. (acetone-hexane) 113°-115° C.
