Versuchsvorschrift
A process for preparing 3-(1,2-diphenylethyl)-1,4,5,6-tetrahydro-1,2,4-triazine which comprises reacting benzyl cyanide with benzyl chloride to produce 2,3-diphenylpropionitrile and cyclizing the 2,3-diphenylpropionitrile with 2-aminoethylhydrazine in the presence of a catalytic amount of elemental sulfur to give 3-(1,2-diphenylethyl)-1,4,5,6-tetrahydro-1,2,4-triazine.
