실험 절차

To a suspension of NaH (60% in mineral oil, 58 mg) in 10 mL of dimethylformamide was added 2-amino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]pyrimidin-7(8H)-one (320 mg, 1.04 mmol). The mixture was heated to 60° C. resulting in a clear solution. 1-Chloro-3-phenylpropane (260 μL, 1.81 mmol) was added, and the reaction mixture was heated at 60° C. for 35 minutes, then poured onto ice water. The resulting gummy solid was dissolved in ethyl acetate, washed with water, and dried over magnesium sulfate. Filtration, followed by concentration in vacuo, gave an oil that was purified by flash chromatography, eluting with 1:3 hexane:ethyl acetate to provide 345 mg of crude product. Recrystallization from ethyl acetate and hexane followed by drying in vacuo provided 253 mg (57%) of 2-amino-6-(2,6-dichlorophenyl)-8-(3-phenylpropyl)-8H-pyrido[2,3-d]pyrimidin-7-one; mp 161°-163° C.
