The same procedures for preparing 1-(3-piperidinopropyl)-3-amino-5-chloroindazole as described in Example 100 were repeated except that 1-(1-methyl-3-bromopropyl)piperidine was employed instead of the 3-bromopropylpiperidine. As a result, 1-(3-piperidinobutyl)-3-amino-5-chloroindazole was obtained.
