Reaction Steps
Dissolve 3-(4-cyanophenyl)-propionic acid (0.4 g, 2.48 mmol) and thionyl chloride (1.1 mL, 14.9 mmol) in toluene (2 mL) and reflux the mixture for 2 h. Concentrate in vacuo, dissolve the residue in DCM (1.5 mL) and add the solution to a cold solution (0° C.) of tert-butylamine (300 μL, 2.85 mmol) in DCM (1.5 mL) and triethylamine (97 μL, 0.69 mmol). Allow the mixture to stir at 0° C. for 15 min and at room temperature for 16 h. Add water, separate the organic phase and extract the aqueous phase twice with DCM. Dry the combined organic extracts over Na2SO4, filter and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (65:35) to obtain the desired intermediate (306 mg, 54%).
