A mixture of 2-(2-bromo-1-methyl-4-phenyl-1H-imidazol-5-yl)-7-(methylthio)-[1,3]thiazolo[5,4-d]pyrimidine (Intermediate 37) (50 mg), tetrakis(triphenylphosphino)palladium(0) (28 mg), sodium carbonate (33 mg) and phenylboronic acid (14 mg) in DME (2 mL) and water (1 mL) was heated at 90° C. for 2 hours. After cooling to ambient temperature and extraction into DCM (3×5 mL), the combined organics were dried, filtered and the solvent evaporated in vacuo to give a brown oil. Purification by flash chromatography on silica eluting with EtOAC:hexane (1:9) gave the title compound as a yellow solid (25 mg, 50%);
