Reaction Steps
To an oven-dried, septaed 25 mL round-bottom flask, cooled under an argon atmosphere, and charged with 24k (125.8 mg, 0.50 mmol) was added 1.25 mL freshly distilled CH2Cl2 under argon. The reaction was cooled to −15 C and to the flask was added cyanuric fluoride (225 μL, 2.5 mmol). The reaction was stirred at −15 C for 15 minutes then anhydrous pyridine (40 μL, 0.5 mmol) was added. Stirring was maintained at −15 C for 60 minutes. Without warming, the crude reaction was poured over ice, and immediately extracted twice with CH2Cl2. The combined CH2Cl2 extracts were washed once with water, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo to afford 115.3 mg of a mixture of 24k and 25k as an off-white solid. FTIR (film) 1849.3 cm−1.
