A suspension of 5-bromo-4-chlorothieno[2,3-d]pyrimidine (1 g, 4.01 mmol) in concentrated aqueous ammonium hydroxide (150 mL, 3852 mmol) was stirred overnight at 90° C. in a sealed vessel. The reaction was allowed to cool to room temperature and filtered. The white solid in the filter was air dried to afford 5-bromothieno[2,3-d]pyrimidin-4-amine (796 mg). LC/MS (ES) m/z=387.1 [M+H]+.
