실험 절차

To a solution of ethyl 1-[5-(3-nitrophenyl)-1,3-thiazol-2-yl]piperidine-4-carboxylate (75 mg, 0.21 mmol) in ethyl acetate (1.9 mL) and acetic acid (0.19 mL) was added 10% palladium on carbon (22 mg, 0.021 mmol), and the mixture was stirred under an atmosphere of hydrogen (balloon) for 3 hours. The mixture was filtered through celite, washing with ethyl acetate and the filtrate concentrated under reduced pressure. Purification by CombiFlash (30-70% ethyl acetate:hexanes) provided 60 mg (0.18 mmol, 87% yield) of ethyl 1-[5-(3-aminophenyl)-1,3-thiazol-2-yl]piperidine-4-carboxylate.
