실험 절차
6-Ethyl-3-(pyrimidin-5-ylamino)-pyridine-2-carboxylic acid ethyl ester (prepared according to US 2006/199960; 200 mg, 0.73 mmol) was dissolved in a THF/ethanol (12 ml/3 ml) mixture, cooled to 0° C. and treated with lithium hydroxide (2.2 ml, 1N aqueous solution). The reaction mixture was allowed to warm-up to ambient temperature and stirring was continued at that temperature for 2 hours. The pH value was subsequently adjusted to acidic and the reaction mixture was extracted with dichloromethane (3×40 ml). The combined organic phases were dried and evaporated to yield the product as light yellow solid (175 mg, 97%).
