Versuchsvorschrift

A solution of 2.7 g (0.02 mol) of 2-acetylpyridine hydrazone in 5 ml of MeOH was treated with 3.1 g (0.03 mol) of allyl isothiocyanate and the solution was heated at reflux for 3 hours. The solution was cooled and the product which formed was collected. The crude material was recrystallized 3 times from MeOH, affording 2.5 g (49%) of white needles of 2-acetylpyridine 4-allyl-3-thiosemicarbazone, mp 107° C.
