Reaction Conditions

Reaction Steps

To a Grignard Reagent prepared from 21.3 grams (0.088 mole) of 1-bromo-4-trifluoromethoxybenzene and 2.5 grams (0.102 gram-atom) of magnesium metal was added a solution of 7.1 grams (0.068 mole) of 4-cyanopyridine in 50 mL of THF. Upon completion of addition, the reaction mixture was stirred at 40° C. for 18 hours. After this time, the reaction mixture was poured into an aqueous dilute solution of ammonium chloride, and was acidified to a pH of 3 with aqueous 10% hydrochloric acid. The mixture was extracted with methylene chloride and the combined extracts were dried with sodium sulfate. The mixture was filtered, and the filtrate was concentrated under reduced pressure to a residue. The residue was purified with column chromatography on silica gel using acetone, methylene chloride, and mixtures thereof as eluants. The appropriate fractions were combined and concentrated under reduced pressure, yielding the subject compound. The NMR spectrum was consistent with the proposed structure.
