To a solution of phenol (94 mg, 1 mmol) in dioxane (5 ml) was added sodium hydride (40 mg of a 60% dispersion in mineral oil, 1.0 mmol). The mixture was stirred at room temperature for 10 minutes. Then, 4-chloro-6-(4-fluorophenyl)-pyrido[3,2-d]pyrimidine (52 mg, 0.2 mmol) was added to this solution. The resulting mixture was stirred at room temperature for another 30 minutes. After concentration under reduced pressure, the residue was purified by silica gel flash chromatography, the mobile phase being a mixture of methanol and dichloromethane, in a volume ratio of 1:60, yielding the title compound (60 mg, yield 95%) as a white solid which was characterised by its mass spectrum as follows: MS (m/z): 318 ([M+H]+, 100).
