الإجراء التجريبي

To a round bottom flask was added the alcohol 20 (106 mg, 0.359 mmol), TEA (36.3 mg, 0.359 mmol) and DCM (10 mL). Ts2O (117 mg, 0.359 mmol) was added in one portion. The reaction was stirred at RT for 4 hrs. The reaction was then concentrated to dryness and purified on a silica gel cartridge using EtOAc:Hex as the eluent to afford 55 mg (34% yield) of 21 as a white solid. Mass Spec (lo-res): Calc'd for C17H19N7O6S: 449.11. found: 450.1 (M+H).
