Procedure

To a mixture of 2-methylthieno[2,3-d]pyrimidin-4(3H)-one (5.0 g) and AcOH (50 mL) was added NCS (4.8 g), followed by heating and stirring at 40° C. for 2 days. The reaction mixture was concentrated under reduced pressure. To the residue was added water, followed by stirring, and the precipitate was collected by filtration and then dried to obtain 6-chloro-2-methylthieno[2,3-d]pyrimidin-4(3H)-one (5.5 g).
