Reaction Steps

A mixture of 51g of 2-(3-dimethylaminopropylthio)aniline, 26g of freshly distilled benzaldehyde and 200 ml of xylene is refluxed under an atmosphere of nitrogen. The water formed in the reaction is collected in a Dean-Stark tube; the theoretical quantity is collected after 4 hours of refluxing. The xylene and any unchanged benzaldehyde are removed on the steam bath at 30 mm of Hg, finally at 2 mm of Hg. Fractionation of the residue yields 56g of the title compound, boiling point 182°-189° C. at 0.4 mm of Hg.
