A mixture of 4-(2-fluoro-5-(tetrahydro-2H-pyran-4-yl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (210 mg, 0.397 mmol) and 5-fluoro-6-methoxypyridin-3-amine (85 mg, 0.595 mmol) in 1.5 mL of THF at 0° C. was treated with sodium bis(trimethylsilyl)amide (0.99 mL of 1.0 M solution in tetrahydrofuran, 0.99 mmol). It was stirred at this temperature for 15 min, then quenched with sat NH4Cl (5 mL) and extracted with 2×10 mL of EtOAc. The combined organic solution was dried with sodium sulfate and concentrated. The residue was purified on a silica gel column and eluted with 10-30% EtOAc in DCM to give the title compound (220 mg, 85% yield) as a brown amorphous solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.65 (s, 1H), 8.56 (d, J=2.6 Hz, 1H), 8.26 (d, J=2.4Hz, 1H), 8.07 (m, 2H), 7.29 (d, J=8.6 Hz, 2H), 7.22 (d, J=8.4 Hz, 2H), 6.91 (d, J=8.6Hz, 2H), 6.85 (d, J=8.6 Hz, 2H), 4.87 (s, 2H), 4.80 (s, 2H), 3.96 (m, 2H), 3.91 (s, 3H), 3.74 (s, 3H), 3.69 (s, 3H), 3.45 (m, 2H), 2.78 (m, 1H), 2.57 (s, 3H), 1.67 (m, 4H). m/z (ESI, positive ion) 652.0 (M+H)+.
