실험 절차

Methyl 3-{[5-(azetidin-1-ylcarbonyl)-3-chloropyridin-2-yl]oxy}-5-[(3S)-tetrahydrofuran-3-yloxy]benzoate (3.75 g, 8.68 mmol) was dissolved in THF (40 mL), 1N sodium hydroxide (8.68 mL, 8.68 mmol) was added followed by water (40 mL) and methanol (1 drop) and the resultant solution stirred at RT for 3 hours. The organics were removed in vacuo, the aqueous solution filtered and extracted with ethyl acetate (30 mL). The aqueous layer was acidified with 2N hydrochloric acid, extracted with ethyl acetate (3×50 mL), and the organic extracts washed with water (10 mL), brine (10 mL) then evaporated to dryness to give the desired material as a white foam (3.53 g).
