실험 절차

A stirred solution of 2-(4-{2-[2-(4′-formylbiphenyl-3-yl)-5-methyloxazol-4-yl]ethoxy}phenoxy)-2-methyl propionic acid ethyl ester (0.711 mmol) in ethanol (8.9 mL) was treated with NaOH (aq) (0.854 mL of a 5M solution), and heated at reflux for 1 h. The hot solution was acidified to pH 1 with 1M HCl (6 mL). The mixture was cooled to ambient temperature, then further cooled to 0° C. before filtering the product. Following washing with H2O, the product was dried under vacuum at 50° C. to yield a white, crystalline solid: Rf=0.14 in 6:4 ethyl acetate:hexanes; MS (EI) 486.1 (M+H)+.
