Reaction Steps

The product of Example 5b) (1.68 g; 0.006 mol) was added to a solution of 1-methyl-1H-3-indazoleamine (0.86 g; 0.006 mol), prepared as described in the Journal of Heterocyclic Chemistry 1979 (16), 783-784, and of triethylamine (2.4 ml; 0.018 mol) in toluene (20 ml). The reaction mixture was stirred at room temperature for 18 h and then the solvent was removed by evaporation at reduced pressure. The residue thus obtained was taken up with 1N NaOH and dichloromethane and transferred to a separatory funnel. The organic phase was separated, dried over Na2SO4 and the solvent was removed by evaporation at reduced pressure. The product thus obtained was transformed into the corresponding hydrochloride by dissolution in ethanol, addition of hydrogen chloride in ethanol and recrystallization from ethanol, to give the desired salt (1.6 g).
