실험 절차

An 80% methanol (225 g), 50 g of isopropyl 4-methyl-2-nitro-5-(4-(trifluoromethoxy)phenoxy)benzoate, and 2.5 g of a 5% palladium carbon were charged into a 500-ml stainless steel autoclave equipped with a stirring device and a thermometer, and a reaction was allowed to proceed under a hydrogen pressure of 0.5 MPa at 30° C. for 6 hr. After the replacement of the air in the autoclave with nitrogen, the reaction solution was filtered using 220 ml of methanol to remove the catalyst. The methanol solution thus obtained was concentrated under the reduced pressure, and 208 ml of water was added to the residue. The precipitated solid was collected by filtration and was dried to give isopropyl 2-amino-4-methyl-5-(4-(trifluoromethoxy)phenoxy)benzoate (43.96 g, yield: 95%).
