Procedure

To a solution of 3.75 g (1.5 mmol) of the compound of Example 39A in 55 ml benzene are added 3 g (18.5 mmol) 3-(trifluoromethyl)aniline and 1.1 g (18.5 mmol) acetic acid. The mixture is stirred under reflux overnight using a Dean-Stark trap to remove water. After removal of the solvent in vacuo, the residue is purified by preparative HPLC (column: YMC C18 ODS-AQ 250 mm×30 mm, 11 μm; solvent A: acetonitrile, solvent B: water; gradient: 0 min 10% A, 3 min 10% A, 11 min 90% A, 13 min 90% A, 13.2 min 10% A, 15 min 10% A; wavelength: 220 nm; injection volume: ca. 900 μl ethanol solution; number of injections: 6). The product containing fractions are combined and concentrated in vacuo.
