Versuchsvorschrift

5-Isopropyl-6-(2,3,5-trimethyl-phenoxy)-1H-pyrimidine-2,4-dione (39 mg, 0.135 mmol) was dissolved in 1.5 mL DMF. Potassium carbonate (31 mg, 2 eq.) was added and the reaction was stirred at room temperature for 10 minutes. Methanesulfonic acid 2-fluoro-6-(4-methoxy-benzylamino)-pyridin-4-ylmethyl ester (0.135 mmol) and lithium iodide (15 mg, 1 eq.) were added. The reaction was stirred at room temperature overnight. Ethyl acetate was added to the reaction mixture, followed by washing with brine. The organic layer was concentrated down and purified (silica gel, 0-80% EtOAC/hexane) to give white powder (25 mg, 42%). LC-MS shows 533.1 (M+1). 1H NMR (300 MHz, CDCl3): δ 8.68 (b, 1H), 7.22 (d, 2H), 6.86 (d, 2H), 6.75 (s, 1H), 6.18 (s, 1H), 5.95 (d, 2H), 4.94 (d, 1H), 4.45 (d, 1H), 4.37 (s, 2H), 3.80 (s, 3H), 2.68 (m, 1H), 2.23 (s, 3H), 2.19 (s, 3H), 2.06 (s, 3H), 1.15 (dd, 6H).
