Procedure
1.0 g of methyl 2-amino-4-(3-pyridyl)-5-methylsulfonylbenzoate [obtainable by reacting methyl 2-amino-4-bromo-5-methylsulfonylbenzoate with pyridine-3-boronic acid] is dissolved in 15 ml of 1-methylpyrrolidone and the solution is stirred for 15 min. Subsequently 0.9 g of guanidinium chloride and 2.6 ml of diisopropylethylamine are added and the mixture is stirred at room temperature for one hour. Customary workup gives N-diaminomethylene-2-amino-4-(3-pyridyl)-5-methylsulfonylbenzamide.
