Reaction Steps

To a stirred, cooled (-20° C.) solution of 3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid (0.52 g) in N,N-dimethylacetamide (5 mL) was rapidly added thionyl chloride (0.39 g) and the mixture stirred at -10° to -20° C. for 1 hour. 3-Methoxy-4-aminobenzophenone (0.50 g) was then added in one portion and the mixture allowed to stir at room temperature overnight. The solution was poured into water and the aqueous phase decanted from the resulting oily solid. Chromatography (eluent methylene chloride then 2% ethyl ether in methylene chloride) gave the title compound (0.37 g) as an off-white solid; mp 126°-128° C. Analysis for C18H16F3NO4.0.25 H2O: Calculated: C, 58.14; H, 4.47; N, 3.77; Found: C, 58.29; H, 4.48; N, 3.78.
