反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 20.5 gm. (0.097 mole) of 3,5-dinitrobenzamide in 450 ml. of an ethyl acetate-ethanol mixture (2:1) is hydrogenated at 3 atmospheres of hydrogen using 1 gm. of 10% palladium on charcoal as catalyst. When absorption of hydrogen is complete, the catalyst is removed by filtration and the filtrate is concentrated to dryness under reduced pressure and the residue recrystallized from water. There is obtained 11.65 gm. (79%) of long yellow needles melting at 108°-9° . When absorption of hydrogen the catalyst is removed by filtration the filtrate is concentrated to dryness under reduced pressure the residue recrystallized from water There is obtained 11.65 gm
