Reaction Steps

Bubble nitrogen for 15 min into a solution of 4-[2-(2,2-dimethyl-propionylamino)-ethyl]-benzonitrile (175 mg, 0.76 mmol) in methanol (31 mL) with concentrated HCl (3 drops). Add 10% Pd/C (Degussa type E101, 18 mg) and submit the mixture to hydrogenation at atmospheric pressure for 64 h. Filter the catalyst through Celite® and concentrate in vacuo to obtain the hydrochloride salt of the title compound. Add saturated aqueous NaHCO3 and extract twice with EtOAc. Dry the combined organic extracts over MgSO4, filter and concentrate in vacuo to obtain the title compound as a yellow oil (110 mg, 62%). MS (ES+) m/z: 235 (M+H)+.
