Procedure

If the procedure indicated is followed but isopropylamine is replaced by propylamine, 22 g of 1-propylamino-7-chloroanthraquinone are obtained. The nitrobenzene/methanol mother liquor is concentrated and the residue is treated with methanol and with a little nitrobenzene. After working up, 8 g of 1-propylamino-6-chloroanthraquinone are obtained.

Workup

  1. customare obtained
  2. concentrationThe nitrobenzene/methanol mother liquor is concentrated
