General procedure for the synthesis of 6-(2,5-dichlorophenyl)-1,3,5-triazine-2,4-diamine x maleate from 6-(2,5-dichlorophenyl)-1,3,5-triazine-2,4-diamine: 6-(2,5-dichlorophenyl)-1,3,5-triazine-2,4-diamine x maleate (0.3 g, 0.80 mmol) was dissolved in ethyl acetate ( 50 mL) and the reaction was stirred with saturated NaHCO3 solution (50 mL) for 1 hour at room temperature. After completion of the reaction, the organic layer was separated and washed with distilled water. The organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the target product 6-(2,5-dichlorophenyl)-1,3,5-triazine-2,4-diamine in 70% yield.
