Reaction Steps

Dissolved 1-(5-nitro-2-pentafluoroethyl-phenoxy)-3-pyrrolidin-1-yl-propan-2-ol (3.5 g) in CH2Cl2 (15 mL), added TEA (2.55 mL) and cooled to 0° C. Acetyl chloride (781.3 μL) was added dropwise, forming a suspension. The mixture was warmed to RT and stirred for 1.5 h. Additional acetyl chloride (200 μL) was added and the mix was stirred for another h. The mixture was diluted with CH2Cl2 and washed with sat. NaHCO3. The organic layer was removed, washed with brine and back extracted with CH2Cl2. Dried the combined organic layers over Na2SO4, filtered and concentrated in vacuo. The residue was purified over silica gel column (5:94.5:0.5 MeOH:CH2Cl2:NH4OH) to provide the titled compound as a yellow brown oil.
