The compound obtained in step A) (1.0 g, 0.026 mol) and 1-naphthyl hydrazine (0.45 g, 0.028 mol) is dissolved in CCl4 (15 ml) and stirred for 10 hours at 25° C. under a nitrogen atmosphere. The reaction mixture is stirred for 12 hours and filtered to remove traces of insoluble particles. The CCl4 solution is then concentrated and a few drops of methanol are added to the residue, wherein a brownish solid is obtained (Yield=0.7 g (56%)).
