Versuchsvorschrift

A 30 mL reaction vial was charged with tert-butyl 2-(3,3-difluoro-2-oxoindolin-1-yl)acetate (275 mg, 1 mmol) as a yellow oil. DCM (3 mL) was added, followed by an equal volume of formic acid. The reaction was stirred for 16 h. The reaction mixture was concentrated under reduced pressure to give 2-(3,3-difluoro-2-oxoindolin-1-yl)acetic acid as a yellow solid. The desired M+H (228) was observed in the LCMS using the method [1] with a retention time of 1.652 min.
