A solution of N,N-bis(4-methoxybenzyl)-4-(2-((6-methoxy-3-pyridinyl)amino)-5-(4-morpholinylcarbonyl)-3-pyridinyl)-6-methyl-1,3,5-triazin-2-amine (0.128 g, 0.193 mmol) in TFA (2.00 mL) at ambient temperature was treated with triflic acid (0.051 mL, 0.579 mmol) and heated for 4 h at 80° C. The reaction mixture was concentrated, but not to dryness. A few ice cubes were added and saturated NaHCO3 (aq.) was added until pH was about 7. The solid was collected by filtration, washed with water and CH2Cl2, and dried under vacuum to give 4-(2-((6-methoxy-3-pyridinyl)amino)-5-(4-morpholinylcarbonyl)-3-pyridinyl)-6-methyl-1,3,5-triazin-2-amine (0.056 g, 0.133 mmol, 68.6% yield) as a brown solid. 1H NMR (400 MHz, d6-DMSO) δ 11.92 (s, 1H); 8.87 (s, 1H); 8.52 (s, 1H); 8.38 (s, 1H); 8.11-8.22 (m, 1H); 7.92 (br. s., 1H); 7.78 (br. s., 1H); 6.85 (d, J=8.80 Hz, 1H); 3.84 (s, 3H); 3.54-3.65 (m, 8H); 2.44 (s, 3H). m/z (ESI, +ve ion) 423.1 (M+H)+.
