Procedure

10.1 g (0.05 mol) of 3-methyl-4-amino-6-phenyl-1,2,4-triazin-5-one, 10 g (0.09 mol) of benzaldehyde, 0.3g of p-toluenesulphonic acid and 300 ml of benzene were boiled for 8 hours under a water separator. Thereafter the reaction mixture was filtered and the solvent was distilled off in vacuo. The residue solidfied after trituration with petroleum ether.
