실험 절차

A mixture of 2-{[(2,6-dichloropyridin-3-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (2.0 g, 6.61 mmol) and 1-ethylpiperazine (3.77 g, 26.88 mmol) was heated in DMSO (20 mL) at 90° C. overnight. After cooling, the mixture was extracted with ethyl acetate (2×100 mL). The organic layer was separated and washed with water and brine. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was evaporated to dryness and purified by CombiFlash chromatography using 0-20% dichloromethane:methanol to provide 2-({[2-chloro-6-(4-ethylpiperazin-1-yl)pyridin-3-yl]methyl}sulfanyl)-6-methylpyrimidin-4-ol (1H NMR (400 MHz, DMSO-d6): δ 1.02 (t, 3H), 2.18 (s, 3H), 2.31 (q, 2H), 2.56 (m, 4H), 3.42 (m, 4H), 4.30 (s, 2H), 6.01 (bs, 1H), 6.78 (d, J=8.4 Hz, 1H), 7.72 (d, J=8.4 Hz, 1H), LRMS (ES) m/z 379.8) and 2-({[6-chloro-2-(4-ethylpiperazin-1-yl)pyridin-3-yl]methyl}sulfanyl)-6-methylpyrimidin-4-ol (1H NMR (400 MHz, DMSO-d6): δ 0.99 (t, 3H), 2.21 (s, 3H), 2.31 (q, 2H), 2.56 (m, 4H), 3.42 (m, 4H), 4.37 (s, 2H), 6.01 (bs, 1H), 7.06 (d, J=7.7 Hz, 1H), 7.77 (d, J=7.7 Hz, 1H), LRMS (ES) m/z 379.8) as a white solid (1.73 g, 3:1 ratio, 69% yield).
