Reaction Steps
To a mixture of (E)-tert-butyl 4-acetoxy-4-(4,4,4-trifluorobut-1-enyl)piperidine-1-carboxylate (200 mg, 0.57 mmol) in methanol (5 mL) was added 2M NaOH (2 mL, 4 mmol), the mixture was held stirring at r.t. for 16 hrs, when TLC (20% EA/PE) indicated completion of the reaction. The mixture was concentrated in vacuo, the residue was diluted with brine and extracted with EtOAc, and the organic layer was concentrated in vacuo to get the crude product, which was used directly for the next step.
