実験手順

A solution of 9.1 ml of 3-bromopropionylchloride in 10 ml of dry benzene was added dropwise to a solution of 10.0 g of 3-phenylindoline and 10 ml of triethylamine in 100 ml of dry benzene cooled to 10° C. The precipitated triethylamine hydrochloride was separated by filtration, the benzene was removed from the filtrate in vacuo at room temperature and the residue recrystallized from ethanol to give 5.6 g of the desired N-(3-bromopropionyl)-3-phenylindoline having a melting point of 98°-9° C.
