Reaction Steps

6.4 g (39 mmol) of N-phenylpiperazine (III) is placed in 2.2 mL of glacial acetic acid, heated to 125° C., then 3.2 g (15 mmol) of 2-ethylsulfanyl-6,7-dihydrothieno[3,2-d]pyrimidin-4-ol (II) is added, and the mixture is heated to 175° C. After 1.5 hours, the resulting solid is stirred with water, suction filtered, washed with ethanol, and dried. 4.3 g product (91%) is obtained as a powder.
