Versuchsvorschrift
Then, 590 mg of 1-benzyl-4-[N-(o-aminobenzyl)amino]-piperidine, 600 mg of sulfurylamide and 12 ml of pyridine are mixed and refluxed with heating for 2 hours. The reaction mixture is cooled to room temperature and poured into 50 ml of ice water. The white crystals deposited are separated by filtration, washed with 10 ml of water and dried to obtain 520 mg of the desired product as crystals.
