Reaction Steps

To a solution of 4-[4-(1-ethyl-propoxy)-3,6-dimethyl-pyridin-2-yloxy]-3,5-dimethyl-phenol (58 mg, 0.176 mmol) in 3 ml of dry THF was added triphenylphosphine (70 mg, 0.264 mmol) and isopropanol (60 mg, 0.22 mmol). The resulting mixture was stirred at room temperature for 5 min, diethyl azodicarboxylate (46 mg, 0.264 mmol) was added. The mixture was stirred at room temperature overnight. An additional 20 mg of diethyl azodicarboxylate was added and the mixture was stirred for an additional 4 hours. The mixture was quenched with water and extracted with methylene chloride. The organic layer was dried and concentrated to give an oil. The oil residue was purified through silica gel column chromatography using 1:1 hexane:chloroform to 1:2 hexane: chloroform as eluent to give 38 mg (58%) of the title compound as a colorless oil. 1H NMR (CDCl3) δ6.60 (s, 2H), 6.28 (s, 1H), 4.50 (m, 1H), 4.18 (m, 1H), 2.20 (s, 3H), 2.19 (s, 3H), 2.079s,6H), 1.71 (m, 4H), 1.34 (d, 6H), 0.98 (t, 6H) ppm.
