Procedure
A solution of 11.1 g of 3-phenylindoline in 60 ml of acetone was cooled to 0° C., 5.1 ml of chloroacetylchloride was added and the mixture poured into an ice cold solution of 10 g of sodium acetate in 50 ml of water. The mixture was then stirred for one hour at room temperature and the residual solid removed by filtration. Recrystallization from ethanol gave a yield of 13.0 g of the desired N-chloroacetyl-3-phenylindoline having a melting point of 76°-78° C.
