Reaction Steps

4-(5-chloro-2-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (1.35 g, 2.242 mmol) (Example 313, Step 2) was dissolved in TFA (22 mL), trifluoromethanesulfonic acid (0.587 mL, 6.73 mmol) was added, and the resulting mixture was stirred at 80° C. for 2 h. The reaction mixture was then concentrated, and the residue was taken up in 400 mL of EtOAc, added to a separatory funnel, partitioned with sodium bicarbonate (saturated, aqueous), washed 4 times with 150 mL of sodium bicarbonate (saturated, aqueous), separated, and concentrated via rotovap to give the title compound as an insoluble yellow solid which was used without further purification. m/z (ESI, +ve ion) 362.0 (M+H)+.
