反应详情

Into a reaction vessel was charged 4-cyano-2-nitrotoluene (12) (300 g) and ethanol, and 10% palladium/carbon (9.5 g) was added to this and a hydrogen catalytic reduction reaction was conducted at room temperature. When absorption of hydrogen disappeared, palladium/carbon was removed by filtration, then, the solvent was distilled off from filtrate, to obtain 4-cyano-2-aminotoluene (13) (132.5 g, yield from (11) is 98%).
