Participants

Reaction Steps

Potassium t-butoxide (0.235 g, 2.1 mmol) is added at room temperature to a solution of 3-{4-[2-(3-chloro-phenylamino)-pyrimidin-4-yl]-pyridin-2-yl}-4-methyl-oxazolidin-2-one (0.5 g, 1.3 mmol). After stirring the mixture for 10 minutes chloromethylmethylether (0.17 g, 2.1 mmol) in THF (3 ml) is added. The mixture is stirred for additional 5 hours at this temperature. Dilution with ethyl acetate, washing with brine, drying over magnesium sulfate, filtering and evaporation of the solvent gives the title compound in form of a slightly colored oil; 1H-NMR (DMSO): 8.70 (s, 1H); 8.51 (d, 1H); 8.48 (d, 1H); 7.68 (d, 1H); 7.47–7.23 (m, 5H); 5.39 (s,2H); 4.87–4.74 (m,1H); 4.50 (dd, 1H); 4.08 (dd,1H); 3.25 (s,3H); 1.33 (d,3H).
