Procedure
A mixture of 2-butyl-benzofuran-3-carboxylic acid [5-(4-tert-butyl-phenyl)-6-hydroxy-naphthalen-2-ylmethyl]-amide (400 mg, 0.79 mmol), prepared in the previous step, bromoacetonitrile (66 μL, 0.95 mmol) and potassium carbonate (547 mg, 3.96 mmol) in 20 mL of DMF was stirred under nitrogen at room temperature for 19 h (overnight). The reaction was diluted with ethyl acetate, extracted multiple times with water, dried (MgSO4) and the solvent removed under reduced pressure to give a light brown solid. Purification of the solid on a 40 g KP-SIL 60 Δ Biotage column gave 2-butyl-benzofuran-3-carboxylic acid [5-(4-tert-butyl-phenyl)-6-cyanomethoxy-naphthalen-2-ylmethyl]-amide (262 mg, 63%) as a white solid, mp 162-164° C.
