    摘要: Diphenyl-2-carboxaldehyde derivatives, prepared by reacting a diphenylamine-2-carboxylic acid benzenesulfonylhydrazide with a base and hydrazine, semicarbazide, thiosemicarbazide or phenylhydrazine, are reacted with a mineral acid to produce acridines. The acridines are useful as intermediates for preparing 9-aminoalkylacridans having pharmacodynamic activity.

    摘要: A process for the production of a lower alkyl-thiosemicarbazide comprising steam distilling an aqueous solution containing hydrazine and an N-lower alkyl-dithiocarbamic acid quaternary ammonium salt thereby to effect pyrolysis while distilling off water, lower alkyl amine and hydrogen sulfide, and cooling the distilland to form crystals of the lower alkylthiosemicarbazide. Advantageously the solution is obtained by reacting carbon disulfide and methylamine in water, followed by addition of hydrazine.
