Phenethyl bromide → 1-(3-fluorobenzyl)-4-phenethoxypyridin-2(1H)-one

Participants

Reaction Steps

According to Scheme 13 Method A: The title compound was prepared from 1-(3-fluorobenzyl)-4-hydroxypyridin-2(1H)-one (1 eq, 0.23 mmol, 0.05 g, Example 19 Step 2) and 1-(2-bromoethyl)benzene (2 eq, 0.46 mmol, 0.06 mL) according to the procedure described for Example 1 Step 2. Microwave conditions: 180° C. for 900s in acetonitrile (2 mL). The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 25 g SiO2) using CH2Cl2/AcOEt 80/20 and by recrystallization in pentane to afford 1-(3-fluorobenzyl)-4-phenethoxypyridin-2(1H)-one (0.13 mmol, 43 mg, 58%) as a white solid.
