Reaction Steps

4-(Dimethylamino)pyridine (0.66 g, 5.41 mmol) was added to the product from Step A in dioxane (10 mL). 4-(Trifluoromethyl)benzoyl chloride (1.13 g, 5.42 mmol) was added to the mixture and the mixture was boiled for approximately 3 hours. The mixture was allowed to cool to room temperature and was poured into hydrochloric acid (100 mL, 1 N). The mixture was extracted with ethyl acetate (3×50 mL) and the combined extracts were dried and evaporated. Chromatography on silicon gel (eluted with ethyl acetate/hexanes) gave the product as a white solid 1.56 g, (91.7%).
