To a stirred solution of 4-(2-fluoro-5-(morpholinomethyl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (0.0602 g, 0.198 mmol) and N-(5-amino-2-chloropyridin-3-yl)methanesulfonamide (Example 330, step 2, 0.0494 g, 0.223 mmol) in DMF (1 mL) in a 5 mL microwave vial, NaHMDS (Aldrich, 1 M in THF, 0.80 mL, 0.80 mmol) was added dropwise at 0° C. The mixture was stirred at 0° C. for 45 min. The reaction mixture was partitioned between saturated aqueous ammonium chloride (30 mL) and 25% isopropanol in chloroform (20 mL). The aq phase was acidified to a pH of about 3 to 4 then extracted with 25% isopropanol in chloroform (2×30 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo to afford a brown residue. Upon addition of MeOH to the residue, a tan precipitate came out. The solid was collected via filtration and washed with MeOH to afford N-(5-(3-(4-amino-6-methyl-1,3,5-triazin-2-yl)-5-(morpholinomethyl)pyridin-2-ylamino)-2-chloropyridin-3-yl)methanesulfonamide (0.0774 g, 77% yield) as a tan solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 12.26 (s, 1H) 9.66 (br. s., 1H) 8.76 (s, 1H) 8.67 (t, J=2.45 Hz, 2H) 8.31 (d, J=1.56 Hz, 1H) 7.74-8.01 (m, 2H) 3.43-3.66 (m, 6H) 3.14 (s, 3H) 2.38-2.48 (m, 7H). m/z (ESI, pos. ion): 505.9 (M+H)+.
