By the method of preparing thiosemicarbazone derivatives by the application of thiosemicarbazide to aldazine in glacial acetic acid, thiosemicarbazones of benzaldehyde, furfural, salicylaldehyde, anisaldehyde, p-tolylaldehyde, m-tolylaldehyde, o-, m- and p-nitrobenzaldehyde, 5-nitrofurfural, p-hydroxybenzaldehyde, p-dimethylaminobenzaldehyde, resorcylaldehyde, piperonal, vanillin, and o-aminobenzaldehyde were obtained. This reaction does not proceed smoothly in alcoholic solution. The application of hydrazine to 2-methyl-4-amino-5-formylpyrimidine in aqueous solution does not yield an azine componnd but invariably forms a monohydrazone.
