2-chloro-5-methylbenzene-1,3-diamine

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 4-chloro-3,5-dinitrotoluene (9.0 gm.) is dissolved in 50% ethanol (30 ml.). Electrolytically reduced iron powder (14.2 gm.) is added and the stirred reaction mixture heated to reflux. Concentrated HCl (1 ml.) in 50 % ethanol (5 ml.) is added dropwise and refluxing continued for one hour. The reaction mixture is allowed to cool slightly and made basic (pH 8) with 20% NaOH, then the iron removed by filtration. The filtrate is taken to dryness under reduced pressure and the residue extracted with hot Skellysolve "B" (700 ml.). The product precipitates in long needles that were collected by filtration (4.57 gm., m.p. 114°-115.5°, 70% yield). the stirred reaction mixture heated to reflux refluxing to cool slightly the iron removed by filtration the residue extracted with hot Skellysolve "B" (700 ml.) The product precipitates in long needles that were collected by filtration (4.57 gm., m.p. 114°-115.5°, 70% yield)
