Participants

Reaction Steps

According to Scheme 27 Step 2: The title compound was prepared from 1-(4-chlorobenzyl)-5-bromopyrazin-2(1H)-one (1 eq, 0.67 mmol, 0.20 g) and 4-methoxyphenylboronic acid (1.5 eq, 1.00 mmol, 0.15 g) according to the procedure described for Example 1 Step 3. Reaction conditions: 1 hour at 80° C. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 10 g SiO2) using CH2Cl2/MeOH (98/2) as the eluent to afford 1-(4-chlorobenzyl)-5-(4-methoxyphenyl)pyrazin-2(1H)-one (0.47 mmol, 0.15 g, 71%) as a beige solid.
