Versuchsvorschrift

To a solution of N-[4-(dimethylamino)-2-nitrophenyl]acetamide obtained in step 11 above (1.0 eq) in MeOH and water was added KOH (1.5 eq) at room temperature and stirred for 5 hrs. Water was added to the reaction mixture and the organic layer was separated, dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford crude product, which, on purification by column chromatography afforded the desired N-(4-amino-3-nitrophenyl)-N,N-dimethylamine. (Yield=65%).
