Reaction Steps

2-Chloro-6-iodo-4-morpholinothieno[3,2-d]pyrimidine 19 (150 mg), 84 mg of 4-isoxazoleboronic acid pinacol ester and 14 mg of bis(triphenylphosphine)palladium(II) dichloride in 0.7 mL of 1M Na2CO3 aqueous solution and 0.7 mL of acetonitrile was heated to 100° C. in a sealed microwave reactor for 10 min. The reaction mixture was evaporated. The crude product was purified by flash chromatography eluting with 0-20% MeOH/DCM to yield 2-chloro-6-(isoxazol-4-yl)-4-morpholinothieno[3,2-d]pyrimidine (85 mg, 67%).
