Procedure

A solution of the product of part (b) (69.0 g) in acetonitrile (600 ml) was stirred with diisopropylethylamine (43.3 g), and anhydrous lithium chloride (14.13 g) for 30 minutes before adding 3,5-bistrifluoromethylbenzaldehyde (55 g) in acetonitrile (200 ml). The reaction was stirred for two hours then the solvent was removed and the residue partitioned between ethyl acetate and water. The organic phase was washed with 10% citric acid (500 ml), water (500 ml), saturated sodium bicarbonate (500 ml) and water (500 ml). The solution was dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography on silica using ethyl acetate/petroleum ether (1:4) to yield the title compound as a pale yellow solid, mp=137°-138° C.; found: C, 59.23; H, 4.79; N, 5.35; C26H24F6N2O3 requires C, 59.32; H, 4.60; N 5.32%.
