To a tetrahydrofuran solution (20 mL) of 3-nitro-4-n-propylaminobenzoic acid (see Working Example 82-1) (1.94 g, 10.8 mmol) was added 10% palladium-carbon (200 mg), a hydrogen atmosphere was substituted in the flask, and this was stirred at room temperature for 6 hours. After the reaction was finished, this was filtered through Celite, and the filtrate was concentrated to yield the title compound (1.68 g, quant.).
