2,2,2-trifluoro-1-piperidin-4-ylethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A suspension of 3.11 g (9.80 mmol) of benzyl 4-(2,2,2-trifluoro-1-hydroxyethyl)piperidine-1-carboxylate and 300 mg Pd/C (10%) in 30 mL of MeOH was hydrogenated at RT and 3 bar hydrogen pressure for 4 hours. The catalyst was filtered off and the filtrate was evaporated down in vacuo. Yield: 1.82 g (quant. yield); C7H12F3NO (M=183.172); calc.: molpeak (M+H)+: 184; found: molpeak (M+H)+: 184; Rf value: 0.20 (silica gel, EtOAc/MeOH/conc. aqueous ammonia 5:5:0.5). was hydrogenated at RT The catalyst was filtered off the filtrate was evaporated down in vacuo
