Yield:109-07-9 >= 99 %Chromat.
Reaction Conditions:
with hydrogen;5% palladium over charcoal in water at 40; for 6 h;
Steps:
9
A 100 ml four-neck flask equipped with a stirrer, a thermometer, a Dimroth condenser, and a gas introduction pipe was loaded with 1-benzyl-3-methylpiperazine 9.5 g (50 mmole), water 50 g, and 5% Pd/C 1.0 g (PE type, 55.27% water content, manufactured by N.E. Chemcat Corp.) and the contents were stirred at 40°C for 6 hours under hydrogen ventilation condition. When the reaction solution was analyzed by GC, a GC chart excluding toluene showed that no 1-benzyl-3-methylpiperazine, a raw material, was detected and only a peak of 2-methylpiperazine was detected. The yield was quantitative (about 99% or higher).
