Versuchsvorschrift

7-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)-3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one (50 mg, 0.185 mmol) was dissolved in DMF (3 mL) and cooled down in a ice/water bath and treated with sodium hydride (60% dispersion) (17 mg, 0.41 mmol) portion wise. After 10 min a solution of 2-(chloromethyl)pyrimidine hydrochloride (37 mg, 0.22 mmol) in DMF (2 mL) was added and the reaction mixture was warmed up to room temperature and quenched with 6 mL of water after it was complete. The reaction mixture was extracted with EtOAc and water and the organic phase was dried, evaporated and purified by silica gel chromatography (95% DCM/MeOH) and then purified by reverse phase chromatography to afford 7-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)-4-(pyrimidin-2-ylmethyl)-3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one.
