Participants

Reaction Steps

To a solution of 1-benzyl-4-[2-ethyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1,2,3,6-tetrahydro-pyridine (D118) (8 g, 19.83 mmol) in EtOAc (300 mL) was added dry Pd/C (8 g, 10%). The reaction mixture was hydrogenated under 55 psi at 50° C. for 12 hr, and then filtered. The filtrate was concentrated in vacuo. The residue was purified by Mass Directed AutoPrep to give 4-[2-Ethyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-piperidine (D119) (2.5 g). MS (ES): C19H30BNO2 requires 315.2. found 316.2 (M+H+).
