Reaction Conditions

Reaction Steps

The product from Example 42B (11.13 g, 20.0 mmol) and 4-(trifluoromethyl)aniline (32.2 g, 200 mmol) were combined in DMF (50 mL). The mixture was stirred at 50° C. under nitrogen overnight. The reaction mixture was evaporated and the residue was diluted with ethyl acetate, treated with 1M HCl, stirred for 10 minutes, and filtered to remove the solid. The organic layer of filtrate was washed with brine, dried with sodium sulfate, filtered and evaporated. The residue was purified by chromatography on silica gel eluting with ethyl acetate/hexane (0 to 1%). The title compounds (500 mg, 5%) were eluted as the first of 2 stereoisomers and were obtained as a mixture of trans diastereomers.
