Procedure
The same procedures as described in Example 1 were repeated except that 4.50 g of 3-aminoindazole and 5.03 g of (1-methyl-3-bromopropyl)-morpholine hydrobromide were employed instead of the 5.66 g of 3-amino-4-chloroindazole and the 4.83 g of 3-bromopropyldiethylamine hydrobromide, respectively. As a result, 1-(3-morpholinobutyl)-3-aminoindazole having the following analytical values was obtained in a yield of 48%.
