실험 절차

4-(Isopropylamino)-2-(methylthio)pyrimidine-5-carboxylic acid (8.38 g, 36.9 mmol) and HATU (21.03 g, 55.3 mmol) were combined in a 250 mL round-bottomed flask followed by the addition of DMF (92 mL). After that ammonia hydrochloride (9.86 g, 184 mmol) and DIEA (32 mL, 184 mmol) were added and the mixture was stirred at room temperature overnight. The solvent was concentrated under reduced pressure and water (150 mL) was added. The resulting suspension was filtered, washed with water and dried under high vacuum overnight to afford 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxamide (8 g, 35.4 mmol, 96% yield); MS (ESI) m/z 227.4 [M+1]+.
