To a 15 mL round-bottom flask was added 4-(2-fluoropyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (0.045 g, 0.219 mmol), N-(5-amino-2-methylpyridin-3-yl)methanesulfonamide (0.049 g, 0.241 mmol), and DMF (2.0 mL). The mixture was cooled to 0° C. under N2. Sodium bis(trimethylsilyl)amide, 1.0 m in THF (Aldrich) (0.178 mL, 0.877 mmol) was then added to the solution in one portion. The now burgundy color mixture was stirred at 0° C. for 10 min then warmed up to rt and stirred for 1 h. The reaction mixture was quenched with sat. NH4Cl and partitioned between water and CHCl3. The aqueous layer was extracted with more CHCl3 (2×10 mL). The combined organic layers were dried over MgSO4 and concentrated. The crude product was purified by column chromatography (16 g, 5% to 10% MeOH in DCM) to afford the desired product as a yellow solid (35 mg).
