Reaction Steps

Similarly, 2.0 g (0.004 mole) of 1,3,5-tris(p-isopropoxyphenyl)-hexahydro-s-triazine, 1.2 g (0.006 mole) of trichloromethyl chloroformate, 3.1 g (0.012 mole) of 1,3-dibenzylthiourea, and 11 g of a 10% aqueous sodium hydroxide solution were used to obtain 1.5 g (28% yield) of 2-benzylimino-3-benzyl-5-(p-isopropoxyphenyl)-tetrahydro-1,3,5-thiadiazin-4-one (compound No. 375) of the formula, ##STR174## as white crystals melting at 141°-142° C.
