A solution of 4-(2-(6-chloropyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (70 mg, 0.126 mmol) in TFA (10 mL) was heated to 80° C. After 24 h, the mixture was concentrated to a slurry. Water (5 mL) was added, followed by the addition of Na2CO3 in batches until the pH was basic. The mixture was filtered and the solid was washed with water, then MeOH, to give the product as a brown solid (39 mg). LCMS (ES, pos.): calcd for C14H12ClN7: 313.1; found: 314.0 (M+H)+. 1H NMR (400 MHz, d6-DMSO) δ 12.16 (s, 1H); 8.87 (d, J=2.74 Hz, 1H); 8.82 (dd, J=7.83, 1.76 Hz, 1H); 8.48 (dd, J=8.80, 2.74 Hz, 1H); 8.39 (dd, J=4.50, 1.76 Hz, 1H); 7.92 (br. s., 1H); 7.78 (br. s., 1H); 7.46 (d, J=8.61 Hz, 1H); 7.01 (dd, J=7.83, 4.70 Hz, 1H); 2.44 (s, 3H).
