実験手順

Sodium iodide (1.4 g, 9.3 mmol) was added to a solution of chloromethyl isopropyl carbonate (750 mg, 4.8 mmol) in acetone (5 mL). The resulting mixture was stirred at room temperature for 2.5 h, followed by addition of 2-(3-(2,6-dichlorophenyl)isoxazol-5-yl)pyridin-4-amine (500 mg, 1.6 mmol). The reaction mixture was then stirred at room temperature for 7 d. The reaction mixture was concentrated under reduced pressure to provide isopropyl 3-(2-(3-(2,6-dichlorophenyl)isoxazol-5-yl)pyridin-4-ylamino)propanoate, which was carried forward without further purification. 1H NMR (CDCl3): 8.56 (d, 1H), 7.96 (s, 1H), 7.62 (m, 1H), 7.42-7.30 (m, 4H), 7.01 (s, 1H), 6.26 (d, 2H), 5.02 (m, 1H), 1.31 ppm (d, 6H).
