A suspension of 6-chloro-3-(pyrimidin-5-ylamino)-pyridine-2-carboxylic acid ethyl ester (98 mg, 0.35 mmol) in THF (1 ml) and ethanol (0.5 ml) was cooled to 0° C. and treated with 1M LiOH (0.7 ml, 0.7 mmol). The ice bath was removed and the reaction mixture was stirred at rt. for 2 h. 1M HCl (0.7 ml, 0.7 mmol) was added and stirring was continued until a precipitate was forming. The reaction mixture was sucked off and the product was obtained upon drying of the precipitate as yellow solid (60 mg, 67%).
