Reaction Steps

Synthesis took place via the stage of the corresponding phthalimide as in Example 3.(f). The hydrazine cleavage was carried out as in Example 3.(g). The free amine was generated at pH 9-10 from the initially produced hydrochloride and was extracted from the aqueous solution with ether. 1H-NMR (DMSO-d6, δ in ppm): 7.65-7.25 (8H), 5.20 (s, 2H), 3.80 (s, 2H), ca. 3.0 (broad signal, NH2)
