실험 절차
To a solution of the compound from preparation 295, (pyridin-3-yloxy)-acetic acid ethyl ester, 300 mg (1.68 mmol) in 15 mL of dioxane was added a solution of 400 mg (16.8 mmol) of lithium hydroxide in 15 mL of water. The solution was stirred for three hours at rt. then acidified to pH=1.0 with 5 N HCl and concentrated to dryness to give a quantitative yield of the crude desired product. MS (ion spray) 154.1 (M+). Crude product was carried on without further purification.
