Procedure

To a solution of ethyl 1-(3,3,3-trifluoropropyl)piperidine-4-carboxylate (3.30 g, 13.0 mmol) in THF (40 mL) and MeOH (40 mL) was added LiOH—H2O (1.64 g, 39.1 mmol). The reaction was allowed to stir for 15 h at which time the solution was filtered to remove undissolved solids and the filtrate concentrated. The resulting material was diluted with water (10 mL), made to pH 5 with HCl (conc), then concentrated in vacuo to yield a white solid (2.9 g, 150%). Mass Spectrum: Calcd for C9H15NF3O2(M+H): 226. Found: 226.
