3-Formylphenylboronic acid → HCID 86618410, compound

Participants

Reaction Steps

2-Chloro-6-iodo-4-morpholinothieno[3,2-d]pyrimidine 19 (300 mg), 130 mg of 3-formylbenzeneboronic acid and 55 mg of Bis(triphenylphosphine)palladium(II) dichloride in 0.6 mL of 1M Na2CO3 and 0.6 mL of acetonitrile was heated to 100° C. in the microwave reactor for 15 min. The reaction mixture was diluted with ethyl acetate (60 mL), and then washed with H2O (40 mL). The organic layer was dried over MgSO4, filtered and evaporated. The residue was purified by ISCO CombiFlash (0-40% ethyl acetate/hexane) to yield 99 mg of 3-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)benzaldehyde.
