According to Scheme 4 Step 1: The title compound was prepared from 2,3-dimethoxy-5-(4-methoxyphenyl)pyridine (1 eq, 0.41 mol, 0.10 g) and 1-(bromomethyl)-4-chloro-2-fluorobenzene (2 eq, 0.82 mmol, 0.18 g) according to the procedure described for Example 6 Step 2. Reaction conditions: 14 hours at 80° C. in acetonitrile. The crude product was purified by silica gel chromatography (AIT Flashsmart prepacked column 10 g SiO2) using cyclohexane/AcOEt 70/30 to 50/50 as eluent to afford 1-(4-Chloro-2-fluorobenzyl)-3-methoxy-5-(4-methoxyphenyl)pyridin-2(1H)-one (0.24 mmol, 0.09 g, 59%).
