Reaction Steps
A solution of trimethylaluminium (2 M in toluene, 2.0 mL, 4.0 mmol) was added dropwise (exothermic) to a solution of 2-methoxyethylamine (300 mg, 4.0 mmol) in dioxane (3 mL) and the resulting mixture was stirred at room temperature for 1 h. Then a solution of 6-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-nicotinic acid (310 mg, 1.0 mmol) in dioxane (3 mL) was added. The resulting mixture was then heated at 85-95° C. for 4 days and then cooled to room temperature and then poured into water and extracted with ethyl acetate which was then washed with brine, dried over sodium sulfate and evaporated. Purification by chromatography (SiO2, dichloromethane:methanol=100:0 to 9:1) afforded the title compound (280 mg, 76%) which was obtained as a colourless oil. MS: m/e=368.1 [M+H]|.
