I have done this reaction on similar compound except this has one double bond, where the other was a diene. What I did before was extract then wash, 99% yield. I thought it odd the procedure given to me from a grad thesis was opposite. I am going to wash first with 1 N HCl. Ill post results in a few hours... Wash with 1 N HCl until acidic, extract with hexanes..wash with brine, filter and remove solvent i.v....should be great...
