Reaktionsschritte

A solution of triflic anhydride (2.0 mL, 11.9 mmol) in CCl4 (10 mL) at 0° C. was treated with a solution of 2-chloroethanol (0.8 mL, 11.9 mmol) and pyridine (0.96 mL, 11.9 mmol) in CCl4 (6.0 mL) which was pre-cooled to 0° C. The reaction mixture was stirred at 0° C. for 45 minutes and then filtered through a pad of Na2SO4. The filtrate was concentrated and used immediately in the next step.
