The reaction mixture was heated to reflux and stirred for 4 h. The reaction mixture was then cooled to room temperature and poured into ice-water (300 ml_) below 10°C. To the reaction mixture was added dichloromethane (DCM) (500 ml_). The layers were separated, and the organic layer was washed with water (200 ml_x2), dried over anhydrous sodium sulfate and concentrated in vacuum to afford 6-(6-methoxypyridin-2- yl)-/V2,/V4-bis((R)-1 , 1 ,1 -trifluoropropan-2-yl)-1 ,3,5-triazine-2,4-diamine (27 g) as a white solid in 90% yield. 1 H NMR (DMSO-de) δ 8.31 -8.12 (m, 2H), 7.92-7.83 (m, 2H), 6.99- 6.97 (m, 1 H), 5.10-4.93 (m, 2H), 3.94 (s, 3H), 1 .35 (m, 6H) ppm.

80% With disodium sulphide In (methylsulfinyl)methane at 5 - 25℃; for 16.25h; Inert atmosphere; 3 Preparation of 6-(4, 6-bis (((R)-1,1,1-trifluoropropan-2-yl)amino)-1,3,5-triazin-2-yl) pyridine-2-thiol (Compound 3). DMSO (100 mL) and 6-(6-chloropyridin-2-yl)-N2, N4-bis((R)-1,1,1-trifluoropropan-2- yl) -1,3,5-triazine-2,4-diamine (AG-881 free base, 10 g, 24.1 mmol) were charged into a 250 mL flask under N2 at 15~20 °C. The resulting solution was stirred for 10 min at 15~20 °C to get a clear brown solution. The reaction mixture was cooled to 5 °C, and was added Na2S (4.2 g, 90% purity, 24.4 mmol) in portions over 5 min at 5~10 °C. The reaction mixture was stirred for 16 h at 20~25 °C, poured into ice water (500 mL) and acetic acid (50 mL) was added at 5~10 °C with stirring. After stirring for 15-30 min at 10-15 °C, the solid was filtered. The wet cake was dissolved in DCM (100 mL), phase separated, and the aqueous layer was discarded. The organic phase was dried with anhydrous Na2SO4, filtered and concentrated under reduced pressure to obtain the crude product as light yellow oil. The crude product was purified by silica gel chromatography (Elutant: DCM/MeOH - 30:1 to 10:1). The pure fractions containing product were combined and concentrated under reduced pressure to afford the purified product as yellow solid which was further dried in vacuum oven at ambient temperature to obtain 6-(4, 6-bis (((R)- 1,1,1-trifluoropropan-2-yl)amino)-1,3,5 -triazin-2-yl)pyridine -2-thiol as a yellow solid (8.0 g, 80% yield). 1H-NMR (400 MHz, DMSO-d6) 12.68-11.90 (m, 1H), 8.68-7.66 (m, 2H), 7.61-7.48 (m, 3H), 5.36-4.86 (m, 2H), 1.37-1.34 (m, 6H). 13C-NMR (101 MHz, DMSO-d6) 179.09, 178.77, 166.12, 165.71, 165.62, 163.46, 142.85, 142.66, 137.97, 137.62, 136.76, 136.35, 127.83, 125.02, 113.60, 112.82, 47.60-47.17, 14.0 (d, J = 16.2 Hz).
