Sodium Hydroxide → 1-[3-(4-tert-Butylphenyl)-2-methylpropyl]-4-methylpiperazine

Participants

Reaction Steps

533 g of 3-(4-tert.butylphenyl)-2-methylpropyl chloride and 714 g of 4-methylpiperazine were stirred for 7 hours at 140° C. and then cooled to +10° C. in an ice bath, and 400 ml of 50% strength sodium hyroxide solution were added slowly, followed by the addition of 500 ml of ether. The organic phase was separated off, dried over sodium hydroxide and distilled to give 640 g of 1-methyl-4-[3-(4-tert.-butylphenyl)-2-methylpropyl]-piperazine of boiling point 135°-140° C./0.3 mbar.
