A mixture of 2,4-dichloro-6-(4-fluorophenyl)-pyrido[3,2-d]pyrimidine (60 mg, 0.2 mmol) and 3-methoxypropylamine (89 mg, 1.0 mmol) in dioxane (5 ml) was stirred at room temperature for 1 hour. After concentration under reduced pressure, the residue was purified by silica gel flash chromatography, the mobile phase being a mixture of methanol/dichloromethane in a volume ratio of 1:80, affording the pure title compound (69 mg, yield 99%) as a white solid which was characterised as follows: MS (m/z): 347 ([M+H]+, 100).
