Procedure
To a solution of 5.86 g of the ester in 200 ml of hot ethanol, 6 ml of 50% NaOH is added. A precipitate forms and the suspension is refluxed for one hour. Two hundred milliliters of water are added to the mixture and enough concentrated HCl to make the mixture acidic. The mixture is stirred 18 hours at room temperature. A solid product precipitates out and is filtered and recrystallized from toluene giving {[7-chloro-3-(2-chlorophenyl)-1,2-benzisoxazol-6-yl]oxy}acetic acid, mp 165°-168° C.
