        * Transfer hydrogenation. The starting material (1 equiv.) was dissolved into methanol with HCO2NH4 or NH2NH2 (20 equiv.). Pd-C 5% or Pd(OH)2 5% was added into the mixture. The resulting mixture was heated to 80oC with N2 inlet for several hours until TLC showed no starting material left. Work up is similar to that of  Parr shaker. Try this procedure, it might be helpful.

I tried to do the reaction in acetic acid but i had some trouble anyway. Do you have any advise? Thanks a lot Rossana Rossana Ferrara PhD student Universitą degli studi di Milano
