Reaction Steps
The same procedures for preparing 1-(3-diethylaminopropyl)-3-amino-4-chloroindazole as described in Example 89 were repeated except that 4.78 g of 3-bromopropylpyrrolidine hydrobromide and 5.66 g of 3-amino-5-chloroindazole were employed instead of the 3-bromopropyldiethylamine hydrobromide and the 3-amino-4-chloroindazole, respectively. As a result, 4.98 g of 1-(3-pyrrolidinopropyl)-3-amino-5-chloroindazole was obtained.
