실험 절차

Stir the mixture of tert-butyl 4-(4-nitro-2-(trifluoromethyl)phenyl)-5,6-dihydropyridine-1(2H)-carboxylate (289 mg, 0.776 mmol), methanol (50 mL) and Pd/C (10%, 25 mg) under hydrogen atmosphere for 30 hrs. Remove H2, filter the mixture and concentrate the filtrate under reduced pressure. Purify the residue with flash chromatography (silica gel, PE:EtOAc=5:1) to afford the desired product (151 mg, 84%).
