Reaction Steps
1-methylpiperidin-4-ol (2.99 mmol, 344.4 mg) was added to a suspension of potassium tert-butoxide in THF (5 mL) and stirred at RT for 30 minutes. 2-fluoro-5-trifluoromethyl nitrobenzene (2.39 mmol, 500 mg) was then added and the reaction mixture was stirred an additional 5 h at RT, at which time LC-MS showed complete conversion to the desired product. The reaction mixture was concentrated and the dark brown residue was taken up in methylene chloride (25 mL). This was washed with water (3×20 mL), dried over sodium sulfate, filtered and concentrated to give the crude product as a yellow oil. Crude material (>90% purity) was taken to the next step without further purification LC-MS: 305.1 (M+H)
