1-Benzylpiperidine-4-carbaldehyde → Hydroxy[1-(phenylmethyl)-4-piperidinyl]acetonitrile

Participants

Reaction Steps

To a solution of 1-(phenylmethyl)-4-piperidinecarbaldehyde (2.35 g, 11.6 mmol)[prepared according to Alfaro-Lopez, J.; et al. J. Med. Chem. 1999, 42, 5359] in THF (160 mL) at 0° C. was added dropwise Et2AlCN (25 mL, 1 M solution in toluene). After 1 h, the solution was partitioned between NaHCO3(sat)-DCM. The aqueous phase was extracted several times with DCM and the combined organic fractions were dried (Na2SO4) and concentrated yielding the title compound as a yellow oil which was used directly without further purification: LCMS (ES) m/e 249 (M+H)+.
