실험 절차

A solution of bromoacetyl chloride (14.17 g) in methylene chloride (30 ml) is added dropwise to a stirred suspension of oxindole (6 g) and AlCl3 (13.31 g) in methylene chloride (200 ml). The reaction mixture is refluxed for 4 hours, cooled to RT, poured with stirring into an ice/water mixture, stirred for 30 minutes, filtered and washed with methylene chloride yielding the desired product as a solid which is recrystallized from isopropanol.
