Reaction Steps

25 g of ethyl 2-(2-methylaminopyrimidin-4-yl)-1H-indole-5-carboxylate were admixed with 200 ml of ethanol and 24.5 g of 33% sodium hydroxide solution, and heated to from 65° C. to 70° C. for 4 h. After cooling, the mixture was filtered with suction and the precipitate was washed with 15 ml of ethanol/water (9:1). 24.5 g (87.6% of theory) of 2-(2-methylaminopyrimidin-4-yl)-1H-indole-5-carboxylic acid sodium salt were obtained (98.1 HPLC area %).
