A solution of 1-(5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-6-(6-chloro-5-methoxypyridin-3-ylamino)pyridin-3-yl)ethanone (85 mg, 0.220 mmol) in 2 mL of THF at 0° C. was treated with methylmagnesium bromide (0.73 mL of 3.0 M solution in ether, 2.20 mmol) and stirred at this temperature for 15 min. It was quenched with ice cold saturated NH4Cl solution and extracted twice with EtOAc. The combined organic solution was concentrated and the residue was purified on a silica gel column and eluted with 50 to 100% EtOAc in DCM to give the title compound (23 mg, 26% yield) as a yellow crystalline solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 12.19 (br., 1H), 8.97 (d, J=2.6 Hz, 1H), 8.50 (d, J=2.6 Hz, 1H), 8.44 (d, J=2.3 Hz, 1H), 8.37 (d, J=2.4 Hz, 1H), 7.95 (s, 1H), 7.80 (s, 1H), 5.21 (s, 1H), 3.94 (s, 3H), 2.47 (s, 3H), 1.49 (s, 6H). m/z (ESI, positive ion) 402.0 (M+H)+.
