실험 절차

According to Scheme 9 Step 1: The title compound was prepared from 5-(4-methoxyphenyl)pyridin-2(1H)-one (1 eq, 3.73 mmol, 0.75 g, Example 7 Step 1) and ethylbromoacetate (1.2 eq, 4.47 mmol, 0.50 mL) according to the procedure described for Example 1 Step 2. The reaction was stirred at 60° C. for 12 hours. The reaction was filtered and concentrated under reduced pressure to yield a yellow oil. The product was triturated from diisopropyl ether to afford ethyl 2-(5-(4-methoxyphenyl)-2-oxopyridin-1(2H)-yl)acetate (3.38 mmol, 0.97 g, 91%) as a white solid.
