To a mixture of 2-(1-azidopropyl)-3-iodo-6-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (0.11 g, 0.29 mmol) and phenylboronic acid (42.9 mg, 0.352 mmol) in 1,4-dioxane (2 mL) was added a 1M solution of sodium carbonate (37.3 mg, 0.352 mmol) in water (0.35 mL) and tetrakis(triphenylphosphine)palladium (0) (16.9 mg, 0.0147 mmol). The reaction mixture was heated at 100° C. overnight. After cooling to rt, the mixture was diluted with EtOAc, washed with water, brine, dried over MgSO4, and concentrated. The residue was purified on silica gel, eluting with 0 to 40% EtOAc in hexane, to provide the desired product (50 mg, 53.4%). LCMS calculated for C18H18N5O (M+H)+: m/z=320.2. Found: 320.3.
