Versuchsvorschrift
According to Scheme 3 Method A: The title compound was synthesized as described in Example 2 Step 2 using 4-(cyanomethyl)phenyl boronic acid (1.5 eq, 0.50 mmol, 80.9 mg) and 1-(4-chlorobenzyl)-5-bromopyridin-2(1H)-one (1 eq, 0.33 mmol, 0.10 g, Example 2 Step 1) as substrates. The crude product was purified by flash chromatography over silica gel (AIT Flashsmart prepacked column 25 g SiO2) using CH2Cl2/AcOEt to afford 2-(4-(1-(4-chlorobenzyl)-1,6-dihydro-6-oxopyridin-3-yl)phenyl)acetonitrile as a yellow solid (0.33 mmol, 110 mg, 98%).
