Reaction Steps
Dissolved 4-(5-nitro-2-pentafluoroethyl-phenoxymethyl)-piperidine (646 mg) in DCE(6.4 mL), then added acetone (136 μl), NaBH(OAc)3 (541 mg) and finally acetic acid (105 μL). Stirred the cloudy yellow solution under N2 at RT overnight. Added another 130 μL acetone and stirred at RT over weekend. Quenched the reaction with 30 mL N NaOH/H2O and stirred 10 min. Extracted with Et2O and the organic layer was brine-washed, dried over Na2SO4, filtered and concentrated in vacuo. Dried under high vacuum for several h to obtain 1-isopropyl-4-(5-nitro-2-pentafluoroethyl-phenoxymethyl)-piperidine as a yellow orange solid.
