N,N-bis(4-Methoxybenzyl)-4-(2-(6-methoxypyridin-3-ylamino)-5-(1-methyl-1H-pyrazol-4-yl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (140 mg, 0.222 mmol) was treated with TFA (10 mL) and heated at 80° C. with a reflux condenser for 18 h. The TFA was removed in vacuo and the residue was treated with 2 M NH3 in MeOH to pH 7 and dry-packed with silica gel. Purification on the ISCO (12 g column, 1-20% MeOH in DCM) gave 4-(2-(6-methoxypyridin-3-ylamino)-5-(1-methyl-1H-pyrazol-4-yl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (71.7 mg, 0.184 mmol, 83% yield) as an orange crystalline solid. m/z (ESI, +ve ion) 390.0 (M+H)+. 1H NMR (400 MHz, d6-DMSO) δ 11.69 (1H, s); 8.87 (1H, d, J=2.5 Hz); 8.55 (2H, t, J=3.1 Hz); 8.18 (1H, dd, J=8.8, 2.7 Hz); 8.12 (1H, s); 7.90 (1H, s); 7.82 (1H, s); 7.77 (1H, s); 6.84 (1H, d, J=8.8 Hz); 3.88 (3H, s); 3.85 (3H, s); 2.46 (3H, s).
