Abstract

PURPOSE: To obtain the titled compound useful as an intermediate for a compound having an inhibiting action on blood platelet aggregation, by reacting a novel pyrimidine compound with an alkali metal boron hydride.
CONSTITUTION: A novel compound shown by the formulaI(R 1 and R2 are H, alkyl, halogen, etc.) is reacted with an alkali metal boron hydride (e.g., sodium boron hydride, lithium boron hydride) to give the desired compound shown by the formula II. The compound shown by the formulaIis in a solvent (e.g., methanol, ethanol) in the reaction which is carried out at room temperature W about 60°C for 1W20hr. For the novel compound shown by the formulaI, for example, 2,4-dichloro- 5,6,7,8-teterahydro[1]benzothieno[2,3-d]pyrimidine is reacted with sodium boron hydride and with chloroaniline in benzene, to give a compound shown by the formulaIwherein R1=R2=H.
