Procedure

A solution of 6.76 g (0.05 mol) of 2-acetylpyridine hydrazone in 10 ml of MeOH was treated with 7.2 g (0.05 mol) of cyclohexyl isothiocyanate and the solution was heated at reflux for 3 hours. The solution was chilled, and the crystals which formed were collected. Recrystallization of the product from 150 ml of MeOH afforded 6.40 9 (46%) of white needles of 2-acetylpyridine 4-cyclohexyl-3-thiosemicarbazone, mp 155° C.
