The choice of introducing N-methylpiperazine instead of unsubstituted piperazine was made since we assumed that a side reaction leading to dimers was a potential risk if unsubstituted piperazine was used However the very slow substitution reaction indicated that this side reaction would be insignificant if a large excess of piperazine was used

N-methyl piperazine have been prepared by two different methods Among the two different methods Method-I is an effective method for the synthesis of Mannich bases The formation of hydrochloride salt in ethanolic solution accelerates the Mannich reaction and hence the product was formed at a faster rate The structure was confirmed by FTIR 1H
