실험 절차

In an autoclave, 0.88 g of (±)-(5-nitro-2,4,6,7-tetramethyldihydrobenzofuran-2-yl)-[4-(4-imidazol-1-ylphenyl)-piperazin-1-yl]carboxamide and 0.5 g of 10% palladium carbon, 10 ml of ethanol and 5 ml of acetic acid were added, followed by stirring overnight under a hydrogen pressure of 10 kg/cm2. The reaction solution was poured into water, neutralized with a 1N sodium hydroxide solution and then extracted with chloroform. The organic layer was washed with saturated saline and then dried over anhydrous magnesium sulfate. After removing magnesium sulfate by filtration and concentrating under reduced pressure, the residue was subjected to silica gel column chromatography (chloroform:methanol=10:1) to obtain 0.56 g of the objective product (melting point: 189-191° C.).
