EXAMPLE 1 3-(1-Piperazinyl)thieno[2,3-b]pyridine maleate A mixture of 3-aminothieno[2,3-b]pyridine-2-carboxylic acid methyl ester (8.00 g), piperazine (6.70 g), and N-methyl-2-pyrrolidinone (80 ml) was heated to 145 C. for 3 hr, under a nitrogen atmosphere. The solution was allowed to cool, diluted with water (400 ml), and extracted with ethyl acetate. The combined extracts were washed with water and brine dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated to give 4.94 g (86.0%) of residual thieno[2,3-b]pyridine-3-amine.
