Procedure

3,5-dichloro-1,2,4-thiadiazole (135 mg, 0.87 mmol) was added to a solution of ethyl 4-ethylpiperidine-4-carboxylate hydrochloride (190 mg, 0.87 mmol) and Triethylamine (264 mg, 2.61 mmol) in THF (9 mL) and stirred at rt for 1 h, giving a suspension, which was filtered, and the filtrate concentrated in vacuo to give ethyl 1-(3-chloro-1,2,4-thiadiazol-5-yl)-4-ethylpiperidine-4-carboxylate as a yellow oil (260 mg, 98%). ESI-MI m/z 304.2 [M+H]+.
