실험 절차

A mixture of 3-aminobenzoic acid (66.12 g, 0.48 mol) and 10% palladiumon-carbon (13.2 g) in 30% aqueous ethanol (1200 mL) was placed in a 4 L stainless steel high-pressure reactor and reduced at 50° C. and 500 psi of hydrogen for 30 h. The mixture was filtered through Celite and the filter cake was washed with ethanol. The solvent was evaporated, boiling ethanol (1 L) was added and the mixture was allowed to stand for 8 days at room temperature. The mixture was filtered and the product was washed with ethanol and then dried in a vacuum oven at 50° C., to give 3-aminocyclohexanecarboxylic acid (39.30 g, 57%) as a white solid.
