2-(4-Methylthiazol-2-ylamino)pyridin-3-ol (0.250 g, 1.21 mmol) and Cs2CO3 (1.18 g, 3.62 mmol) were added to DMF (3 mL). 3-Bromocyclohex-1-ene (0.216 g, 1.21 mmol) was added, and the reaction mixture was stirred for 3 hours. Water was added and the reaction mixture was extracted with ether. The organic layer was dried, filtered, and concentrated. The residue was purified by silica gel chromatography provide 3-(cyclohex-2-enyloxy)-N-(4-methylthiazol-2-yl)pyridin-2-amine (0.130 g=37.5%). 1H NMR (d6-DMSO) δ 9.53 (s, 1H), 7.85 (dd, 1H), 7.41 (d, 1H), 6.90 (dd, 1H), 6.58 (s, 1H), 6.00 (m, 1H), 6.88 (m, 1H), 6.88 (m, 1H), 4.99 (m, 1H), 2.24 (s, 3H), 2.05 (m, 2H), 1.87 (m, 3H), 1.62 (m, 1H); Mass spectrum (apci) m/z=288.0 (M+H).
