Reaction Steps

Combine 2,2,2-trifluoro-ethanol (6.2 mL), pyridine (6.8 mL) and CH2Cl2 (20 mL) cooled in an ice bath. Add Tf2O (25 g) over about 45 minutes. After 15 minutes, add water, separate the layers and extract with water. The organic layer was dried over Na2SO4 and concentrated through a short path distillation apparatus (8 g, 54%).
