The reaction was microwaved for 10 minutes at 180C. The reaction was allowed to cool. The reaction was then filtered and concentrated under reduced pressure. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 15g SiO2) using CH2Cl2/AcOEt (80/20, Rf=0.3). The product was further purified by reverse phase C18 column using water/acetonitrile 60/40 to afford 1- (cyclohexylmethyl)-5-(4-methoxyphenyl)pyridin-2(lH)-one (0.11mmol, 32mg, 31%) as a colorless oil.

Then, the reaction was cooled to room temperature. The suspension was filtered off and the filtrate was evaporated under reduced pressure. The residue was puridied by short open column chromatography CEta2Cl2/MeOEta(NEta3)sat. 1% yielding l-((6-chloropyridin-3-yl)methyl)-5-(4- methoxyphenyl)pyridin-2(lH)-one as white solid (1.04g, 75%) |

The reaction was stirred at room temperature for 30 minutes then l-(2- bromoethoxy)benzene (3eq, 0.90mmol, 0.18g) was added. The reaction was stirred at 60C for 12 hours. After concentration of the solvent, acetonitrile (3mL) was added followed by K2CO3 (10eq, 3.00mmol, 0.4Ig) and l-(2-bromoethoxy)benzene (10eq, 3.00mmol, 0.60g) then the reaction was microwaved for 5 minutes at 180C. The reaction was filtered and concentrated under reduced pressure. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 10g SiO2) using CEta2Cl2/AcOEt (80/20) as the eluent to afford 5-(4-methoxyphenyl)-l- (2-phenoxyethyl)pyridin-2(lH)-one (0.13mmol, 42mg, 44%) as a yellow oil.
