To a 2,4-dimethylthiazole-5-carbohydrazide (Prep26, 23 g, 0.13 mol) in ethanol (100 ml), methyl isothiocyanate (49.1 g, 0.67 mol) was added. The mixture was refluxed overnight. Then the ethanol was partially removed under vacuum and the residue was filtered. The solid was dried under vacuum to afford 14 g of the title compound (y=46%).
