실험 절차
To a solution of 5.0 g (19.6 mmol) of ethyl 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxylate in 20 mL of ethanol is added a solution of 0.8 g (20.6 mmol) of sodium hydroxide in 30 mL of water. The reaction suspension is stirred at room temperature overnight. The reaction solution is diluted with 100 mL of water and washed twice with diethyl ether. The aqueous phase is neutralized with 20.6 mL of 1N HCl. The precipitate is filtered and washed twice with water, dried under vacuum at 70° C. to give 4.0 g (90%) of the title compound: mp 202-203° C. (dec).
