実験手順

6-Bromoquinolin-2(1H)-one (5.03 g, 22.5 mmol) was subjected to protocol K with ethyl bromoacetate instead of methyl bromoacetate to afford 6.96 g (100% yield) of ethyl 2-(6-bromo-2-oxoquinolin-1(2H)-yl)acetate as a white solid. Method [7] Retention time 4.79 min by HPLC (M+=310 and 312) and (M+Na=332 and 334). The acetate (318 mg, 1.03 mmol) was subjected to the protocol in Example 1.53.4 to afford 228 mg (83% yield) of 2-(6-bromo-2-oxoquinolin-1(2H)-yl)acetic acid as a white solid. Method [8] Retention time 4.79 min by HPLC (M+=282 and 282) and (M+Na=304 and 306).
