The mixture was heated to reflux for 16 hours. After cooling to room temperature, the reaction solution was acidified with 1N HCl to pH=3. All solvents were removed under vacuum. The residue was purified by prep. HPLC to give 4-(4-(2-(2-aminoethylamino)ethylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoic acid (40 mg).
