Reaction Steps
4-(2,2-Dimethyl-propylamino)-6-hydroxy-quinazoline-2-carbonitrile (0.23 mmol), 4-chloromethyl-pyridine hydrochloride (0.35 mmol) and cesium carbonate (2.3 mmol) are stirred in DMF (3 ml) at RT for 20 hours. Water is added until a clear solution is formed. Then more water is added until the solution gets turbide. The precipitate formed is filtered off, washed with water and dried (vacuum). A powder with mp. 203-205° C., Rf=0.2 (CH2Cl2/MeOH=15:1) is obtained.
