1.9 g of benzoguanamine and 3.6 g of nicotinic acid chloride (or an equivalent amount of the hydrochloride) are dissolved in 70 ml of pyridine and heated at 60° C for 6 hours. The reaction mixture is processed as described in Example 4 to yield 0.17 g of 2-amino-4-nicotinamido-6-phenyl-s-triazine [mononicotinoylbenzoguanamine] and 1.2 g of 2,4-bis(nicotinamido)-6-phenyl-s-triazine [dinicotinoylbenzoguanamine].
