Using a procedure similar to that described in Example 1, except replacing the 3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid with 3,3-difluoro-2-difluoromethyl-2-hydroxypropanoic acid and the 4-amino-3-methylbenzophenone with 4-amino-2-bromobenzophenone, the title compound was prepared; mp 128°-132° C. Analysis for C17H12BrF4NO3 : Calculated: C, 47.13; H, 2.79; N, 3.23; Found: C, 56.21; H, 2.95; N, 3.14.
