Triethylamine → N-(5-tert-butyl-1,3,4-thiadiazol-2-yl)-2-fluoro-5-(trifluoromethyl)benzamide

Participants

Reaction Steps

To a solution of 5-tert-butyl-1,3,4-thiadiazol-2-amine (1.57 g, 10 mmol) and 2-fluoro-5-(trifluoromethyl)benzoyl chloride (2.27 g, 10 mmol) in CH2Cl2 (45 mL) at 0° C. was added triethylamine (1.7 mL, 12 mmol) dropwise and the reaction mixture was allowed to warm to ambient temperature for 12 hours. The mixture was then washed with water, brine, dried with MgSO4, filtered, and concentrated under reduced pressure to afford 3.2 g of the title compound. MS (DCI/NH3) m/z 348 (M+H)+.
