Reaction Steps
A mixture of {{2-{5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-6-fluoro-1,2-benzisoxazol-3-yl}-p-tolyl}oxy}acetic acid, methyl ester (10.9 g, 0.0190 mol), 10% hydrochloric acid and acetic acid is stirred two hours at 90° C., cooled, poured into water and extracted with ethyl acetate. The organic layers are combined, washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to a foam. The foam is recrystallized from ethyl acetate to afford the title compound as a white solid (6.20 g, 66.2%, mp 123-126° C.).
