Versuchsvorschrift

The title compound of Example 7 [8-(2,6-difluorophenyl)-4-(4-fluoro-2-methylphenyl)-2-methanesulfonyl-8H-pyrido[2,3-d]pyrimidin-7-one] (0.89 g, 0.002 mol) in dry THF, stirring at 23°, under Ar, was treated with ethylenediamine (668 uL, 0.01 mol). The color became bright orange. LC MS showed no starting material after 5 min. Reaction was stripped to dryness; the residue taken up in ethyl acetate-water. The layers were separated and the aqueous phase adjusted to pH 10.5 with 10% NaOH. Aqueous phase was extracted twice with ethyl acetate; combined organic layers were dried (Na2SO4), then evaporated to give 0.762 g (89%) of the title compound as an amber glass. LC MS (m/e)=426 (MH+). Rt=1.52 min.
