실험 절차
To a solution of 3-nitro-5-trifluoromethyl-pyridine-2-carbonitrile (1194 g, 5500 mmol) in EtOAc (12 l) was added 450 g Pd/C (10%) and hydrogenated (1.1 bar) at ambient temperature for 7 days. The reaction mixture was filtered and concentrated. The crude product was recrystallized from heptane/DCM to give 880 g of the desired product as a yellowish solid.
