Participants

Reaction Steps

According to Scheme 25 Step 2: The title compound was prepared from 1-(4-chlorobenzyl)-5-bromopyridin-2(1H)-one (1 eq, 3.30 mmol, 1.00 g, Example 2 Step 1) and 4-(hydroxymethyl)phenylboronic acid (1.5 eq, 5.00 mmol, 0.76 g) according to the procedure described for Example 1 Step 3. Reaction conditions: overnight at 80° C. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 70 g SiO2) using CH2Cl2/MeOH 98/2 as the eluent to afford 1-(4-chlorobenzyl)-5-(4-(hydroxymethyl)phenyl)pyridin-2(1H)-one (1.72 mmol, 0.62 g, 52%) as a brown oil LC (XTerra RP18, 3.5 μm, 3.0×50 mm Column): RT=3.47 min; MS m/z (CI) [MH]+=326, 328.
