1-Benzyl-4-piperidone → HCID 15402477, compound

Participants

Reaction Steps

To a solution of (S)-1-phenylethanamine (1.921 g, 15.85 mmol) in benzene (8.81 ml) were added molecular sieves in water and 1-benzylpiperidin-4-one (2.50 g, 13.21 mmol). The reaction was stirred at room temperature for 5 hrs. The product mixture was filtered and concentrated under reduced pressure to give a yellow oil, which was standing under vacuum at 45° C. for 14 hrs to remove the residual reactant, yielding (S)—N-(1-benzylpiperidin-4-ylidene)-1-phenylethanamine (3.24 g, 11.08 mmol, 84.0% yield) as a yellow oil. 1H NMR (400 MHz, methanol-d4) δ 7.33-7.25 (m, 10H), 4.81-4.76 (m, 1H), 3.54 (s, 2H), 2.72-2.33 (m, 8H), 1.47 (d, J=6.6 Hz, 3H). LCMS (method K) m/z 291.3 ([M+H]+).
