Participants

Reaction Steps

After ten minutes a solution of trifluoromethanesulfonyl chloride (11.84 g., 0.07 mole) in acetone (150 ml.) is added over 10 minutes. After 15 minutes of stirring the precipitated salts are filtered and the acetone is evaporated at reduced pressure to leave an oil which upon trituration with hexane gives 15 g. of (6,7-dichloro-1-oxo-2-methyl-2-phenyl-5-indanyl)acetic acid which melts at 105°-107° C.
