(1-Oxo-2-bromo-2-ethyl-6-chloro-5-indanyloxy)acetic acid is prepared by following substantially the same procedure as described in Example 1, Step B, using the following reagents: (1-oxo-2-ethyl-6-chloro-5-indanyloxy)acetic acid (13.44 g., 0.05 mole), bromine (8.79 g., 0.055 mole), acetic acid (135 ml.) and 48% hydrobromic acid (2 drops). The crude yield of the product is 17.38 g. (100%), m.p. 157°-159° C. Recrystallization from benzene gives (1-oxo-2-bromo-2-ethyl-6-chloro-5-indanyloxy)acetic acid as white needles, m.p. 159.5°-160.5° C.
