| titleOfInvention | Process for preparing 1-(trialkoxybenzyl) piperazines |
| abstract | SPECIFIC The invention relates to the preparation of (trialcoxy benzyl) -1 piperazines and in particular of (2,3,4,4-trimethoxy benzyl) -1 piperazine. the process consists in preparing, in a first phase, the piperazinone-2 corresponding to said piperazine, then to reduce, in a second phase, said piperazinone. More specifically, in the first phase, a mole is reacted in a first solvent of a trialkoxy benzyl chloride on two moles of piperazinone-2 to obtain a trialcoxy benzyl-4 piperazinone-2 and, in the second phase, we reduce this last compound, in a second solvent, using a hydride. preferably the first solvent is toluene, the second solvent tetrahydrofuran and said hydride AlLiH4 or B2H6.
