benzylic carboxylic acid deoxygenation to alkane.


My aim was the deoxygenation of isonicotinic acid to 4-piridine-alcohol. The reagent was Zn dust / AcOH 24 hours reflux . Surprised me, the yield of 4 picoline was almost 40%, and the alcohol less. Any idea or reference about the mechanism? I cant find it.
