Participants

Reaction Steps

To a solution of 0.3 g (1.055 mmol) of 8-pyrimidin-4-yl-3,4-dihydrospiro[pyrimido[1,2-a]pyrimidine-2,3′-pyrrolidin]-6(1H)-one dissolved in 5 ml of tetrahydrofuran at room temperature were added 0.18 ml (1.27 mmol) of triethylamine and 0.152 ml (1.27 mmol) of 3-fluoro-benzoyl chloride. The resulting mixture was stirred at room temperature under nitrogen atmosphere for 2 h. The reaction mixture was added to a saturated aqueous solution of ammonium chloride, extracted with a mixture of dichloromethane/methanol in the proportions of 100/0 to 80/20, dried and evaporated. The residue was purified by chromatography on silica gel eluting with a mixture of dichloromethane/methanol in the proportions of 100/0 to 70/30 to give 0.310 g (72%) of pure product as grey solid. Mp: 296-298° C.
