실험 절차
Methyl 2-isopropoxy-5-nitrobenzoate (6.92 g, 28.95 mmol) was taken up in THF/H2O (35 ml of each) and LiOH (1.39 g, 57.9 mmol) was added. The mixture was stirred at RT overnight then the pH was lowered to 1 by the addition of concentrated HCl and the product extracted in ethyl acetate (50 ml). The organic layer was dried (MgSO4) and evaporated to give 2-isopropoxy-5-nitrobenzoic acid (6.02 g, 92.5%) as a yellow solid.
