Procedure
In the same manner as described in Example 2, the 7-amino-1,4-benzodioxane-5-carboxylic acid was treated with the methanol, and then the obtained carboxylic ester was reacted with N-methyl piperazine. 5[(4-methyl-1-piperazinyl)-carbonyl]-7-amino-1,4-benzodioxane was obtained (M.P.: 170° C.)
