Tetrahydrofuran → Methyl-[1-(4-ethoxy-phenyl)-piperidin-4-ylmethyl]-amine

Participants

Reaction Steps

[1-(4-Ethoxy-phenyl)-piperidin-4-ylmethyl]-carbamic acid tert-butyl ester (963 mg, 2.88 mmol, prepared in accordance with Example 106) is added to a molar solution of lithium aluminium hydride in tetrahydrofuran (10 mL, 10 mmol) and the resulting mixture is refluxed for 2 hours. After cooling with an ice bath, water (1 mL) is added carefully and the mixture is stirred overnight at room temperature. The reaction is then filtered and the filtrate is concentrated under reduced pressure. The residue obtained is dried under high vacuum to afford the desired product (701 mg; 2.83 mmol).
