Participants

Reaction Steps

This compound was prepared in an analogous manner to that of Example 25d with the replacement of 3-(3-fluorophenyl)glutaric acid with 3-(3,5-difluorophenyl)glutaric acid (9.02 g, 36.9 mmol) and an increase of the heating time from 10 min to 30 min. Chromatography of the collected product on a column of Silica Gel 60 (51×450 mm) with methanol: dichloromethane (4:96) gave a material which was recrystallized from water to give 1.93 g (23%) of 2-(4,6-difluoro-3-oxo-1-indanyl)acetic acid: m.p., 170°-172° C.;
