To a mixture of 7-(1-azidoethyl)-6-bromo-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.12 g, 0.38 mmol) and (2-fluorophenyl)boronic acid (0.064 g, 0.46 mmol) in 1,4-dioxane (4 mL) was added a 1 N solution of sodium carbonate in water (0.8 mL, 0.8 mmol) and dichloro(bis{di-tert-butyl[4-(dimethylamino)phenyl]phosphoranyl})palladium (0.014 g, 0.019 mmol). The mixture was stirred at 100° C. overnight. After cooling, the mixture was diluted with ethyl acetate, washed with water, dried over Na2SO4, concentrated, and purified on silica gel (0-35% ethyl acetate/hexane) to give the desired product (87 mg). LCMS calculated for C15H13FN5OS (M+H)+: m/z=330.1. Found: 330.0.
