実験手順
A mixture of 2-bromo-1,3-thiazole (522 mg, 3.18 mmol) and ethyl piperidine-4-carboxylate (1 g, 6.36 mmol) was heated to 100° C. neat overnight, then cooled to room temperature. The residue was dissolved in dichloromethane and directly purified by CombiFlash (0-40% ethyl acetate/hexanes) to provide 654 mg (2.7 2 mmol, 86% yield) of ethyl 1-(1,3-thiazol-2-yl)piperidine-4-carboxylate as a colorless oil.
