Reaction Steps

To a solution of 79 (1.66 g, 10 mmol) in chloroform (50 mL) was introduced chlorine gas at −5° C. over 15 minutes. The color of the reaction mixture changed from colorless to light blue, green, and finally yellow. After an additional 15 minutes, the reaction mixture was concentrated under reduced pressure to give 80 (2.0 g, 100%) as a yellow oil.
