実験手順

A solution of 4.0 g N-bromosuccinimide in 40 ml anhydrous DMF (dimethylformamide) was added dropwise at 5° C. (ice bath) over 20 minutes to a solution of 6.0 g 2,2-dimethyl-N-[2-(2,3-dihydro-1H-indol-2-yl)phenyl]propanamide in 60 ml DMF. After stirring for one hour additionally, the resulting solution was poured into excess water and the precipitated solid was collected, washed, and taken up in Et2O. The extract was washed with water and brine, dried (MgSO4) and concentrated to give 7.2 g solid. Recrystallization from cyclohexane gave 2.2 g needles, m.p. 173°-175° C.
