Procedimiento

The same procedures for preparing 1-(3-diethylaminopropyl)-3-amino-4-chloroindazole as described in Example 89 were repeated except that 8 g of 3-phthalimidoindazole and 10 g of 3-bromopropylpiperidine hydrobromide were employed instead of the 3-phthalimido-4-chloroindazole and the 3-bromopropyldiethylamine hydrobromide, respectively. As a result, 12.3 g of 1-(3-piperidinopropyl)-3-aminoindazole was obtained.
