To a 15 mL RB flask was added N-(5-amino-2-chloropyridin-3-yl)morpholine-4-sulfonamide (0.065 g, 0.222 mmol), 4-(2-fluoropyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (0.055 g, 0.266 mmol), and DMF (3.0 mL). The mixture was cooled to 0° C. under N2. sodium bis(trimethylsilyl)amide, 1.0 m in THF (Aldrich) (0.888 mL, 0.888 mmol) was added to the solution in one portion. The now dark brown 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 extracted with CHCl3 (3×10 mL). The combined organic layers were dried over MgSO4 and concentrated. The crude product was purified by column chromatography (24 g, 3% MeOH in DCM) to afford the desired product as a yellow solid (42.0 mg).
