Participants

Reaction Steps

In 182 mL of methanol, 26.0 g of 3-{5-[4-(cyclopentyloxy)-2-hydroxybenzoyl]-2-[(3-hydroxy-1,2-benzisoxazol-6-yl)methoxy]phenyl}propionic acid methyl ester was suspended. After dropping 78 mL of water of 10.5 g of sodium hydroxide at room temperature, the result was stirred for 30 minutes at the same temperature. The reaction mixture was added to water. After adjusting to pH 1.5 with a 6 mol/L hydrochloric acid, solids were filtered. The obtained solids were dissolved in a mixture solution of chloroform and methanol. After washing with water, solvent was distilled off under reduced pressure to obtain 22.5 g of 3-{5-[4-(cyclopentyloxy)-2-hydroxybenzoyl]-2-[(3-hydroxy-1,2-benzisoxazol-6-yl)methoxy]phenyl}propionic acid in the form of a light yellowish solid.
