Reaction Steps

A stirred mixture of 4-chloro-5-phenylthieno[2,3-d]pyrimidine (2.2 g, 0.009 mol), furfurylamine (1.26 g, 0.013 mol), triethylamine (1.3 g) and ethanol (20 ml) was heated under reflux for 2 hours then cooled to ambient temperature and poured into water (50 ml). The resulting solid was collected by filtration, washed with water (30 ml), dried in vacuo and crystallised from a mixture of hexane and toluene to give furan-2-ylmethyl-(5-phenyl-thieno[2,3-d]pyrimidin-4-yl)-amine as a pale yellow solid, m.pt. 77-79° C.
