Versuchsvorschrift

2-Methyl-3-nitrobenzamide (8.85 g) was dissolved in a mixture solvent of ethanol (300 ml) and tetrahydrofuran (200 ml), followed by addition of 10% palladium-carbon (800 mg). The resulting mixture was stirred under hydrogen atmosphere at ambient temperature and atmospheric pressure for 6 hours. After insoluble materials were filtered off, the filtrate was concentrated under reduced pressure and washed with isopropyl ether, to afford the entitled compound as white solid (6.73 g, 91%). The physico-chemical values are as follows.
