反応手順
A solution of ethyl 4-bromobenzoylacetate (14.8 g, 0.05 mol) and 9-hydroxyxanthene (10.9 g, 0.06 mol) in ethanol-acetic acid (1:1, 150 ml) was stirred as described in Example 3 (ii) and a white solid collected. The filtrate was stirred a further 3 days and a second crop collected to give ethyl 2-(4-bromobenzoyl)-2-(9H-xanthen-9-yl)acetate.
