Triethylamine → N-(5-tert-butyl-1,3,4-thiadiazol-2-yl)-5-chloro-2-methoxybenzamide

Participants

Reaction Steps

To a solution of 5-tert-butyl-1,3,4-thiadiazol-2-amine (1.57 g, 10 mmol) and 5-chloro-2-methoxybenzoyl chloride (2.05 g, 10 mmol) in CH2Cl2 (45 mL) at 0° C. was added dropwise triethylamine (1.7 mL, 12 mmol) and the reaction mixture was allowed to warm to ambient temperature for 12 h. 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. 1H NMR (300 MHz, DMSO-D6) δ ppm 1.43 (s, 9H), 3.88 (s, 3H), 7.22 (d, J=8.8 Hz, 1H), 7.45-7.76 (m, 2H), 12.43 (s, 1H). MS (DCI/NH3) m/z 326 (M+H)+.
