Procedure
4-(2-(5-Fluoro-6-methoxypyridin-3-ylamino)-5-(2-morpholinopropan-2-yl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.363 g, 0.522 mmol) in TFA (3 mL) was treated with trifluoromethanesulfonic acid (0.232 mL, 2.61 mmol). The reaction was sealed and heated at 80° C. for 30 min, cooled, and poured onto ice. The mixture was basified with 10 N NaOH and the reaction was partitioned between water and DCM. The aqueous layer was extracted with DCM (3×) and the combined organic extracts were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. This material was dissolved in DMSO and purified by prep HPLC (10-55% MeCN/H2O with 0.1% TFA). Product-containing fractions were treated with sat'd aq. NaHCO3 and DCM. The aq. layer was extracted with DCM (3×) and the combined organic extracts were dried over sodium sulfate, filtered, and concentrated in vacuo to give 4-(2-(5-fluoro-6-methoxypyridin-3-ylamino)-5-(2-morpholinopropan-2-yl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (0.069 g, 0.152 mmol, 29.1% yield). m/z (ESI, +ve ion) 455 (M+H)+. 1H NMR (400 MHz, d6-DMSO) δ 11.91 (s, 1H); 8.90 (d, J=2.5 Hz, 1H); 8.48 (d, J=2.5 Hz, 1H); 8.33-8.44 (m, 2H); 7.88 (br. s., 1H); 7.73 (br. s., 1H); 3.93 (s, 3H); 3.57 (br. s., 4H); 2.44 (s, 3H); 2.36-2.43 (m, 4H); 1.35 (s, 6H).
