실험 절차

N-(2-tert-Butyl-5-nitro-phenyl)-2-dimethylamino-acetamide (25.8 g, 92 mmol) was dissolved in EtOH (1.4 L) and 1,4-dioxane (200 μL). The solution was degassed under vacuum with stirring. 10% Pd/C (2.5 g) was added (as a slurry in EtOH). The mixture was degassed again, then the reaction vessel was charged with H2 gas (balloon) and stirred overnight at RT. The reaction was filtered through Celite® with MeOH and the filtrate was concentrated under reduced pressure. The recovered material was eluted through a 36×7 cm column of silica gel with a 97.5:2.5:0.25 and 95:5:0.5 CH2Cl2:MeOH:NH4OH(aq) step gradient giving N-(5-amino-2-tert-butyl-phenyl)-2-dimethylamino-acetamide as a brown solid.
