Reaction Steps

According to Scheme 1 Step 2: K2CO3 (10 eq, 0.11 mmol, 16.0 g) and 1-(bromomethyl)-4-chloro-2-fluorobenzene (1.5 eq, 17.0 mmol, 3.90 g) was added to a solution of 5-bromopyridin-2(1H)-one (1 eq, 11.0 mmol, 2.00 g), in THF (100 mL). The suspension was stirred for 2 hours at room temperature and 17 hours at 60° C. The reaction mixture was filtered and the mother liquor was concentrated under reduced pressure. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 70 g SiO2) using CH2Cl2/AcOEt 80/20 as eluent to afford the title compound 1-(4-chloro-2-fluorobenzyl)-5-bromopyridin-2(1H)-one (9.10 mmol, 2.87 g, 79%) as a white solid.
