Reaction Steps

Dry DMF (5 drops) was added to a mixture of 6-nitrobenzothieno[3,2-d]pyrimidone (161 mg, 0.65 mmol) and oxalyl chloride (0.28 mL, 3.2 mmol) in 1,2-dichloroethane (5 mL). The reaction was heated at 85° C. for 7.5 hours then cooled to 25° C. The solid was Buchner filtered and washed with CH2Cl2 and air dried. 4-Chloro-6-nitrobenzothieno[3,2-d]pyrimidine was obtained as a gray solid (166 mg, 96% crude).
