실험 절차
A solution of 33.5 g of 2-hydroxy-N,N-dimethyl-3-nitrobenzamide in 600 ml of ethanol was added to a suspension of 3.35 g of Pd/C 10% in 70 ml of ethanol. The reaction medium was stirred under 2 bar of hydrogen overnight. TLC and HPLC control (t=0.66 M+181). The reaction medium was filtered through celite and the filtrate was evaporated. 29 g of 3-amino-2-hydroxy-N,N-dimethylbenzamide were obtained in the form of an oily brown solid. Yield=100%.
