実験手順

4-Cyano-3-(4-phenyl-butoxy)-benzoic acid methyl ester from step 1 (285.1 mg, 0.92 mmol) was dissolved in THF (4.6 ml). LiBH4 in THF (2M, 923 μl, 1.85 mmol) was added. The reaction mixture was heated to 70° C. for 3 hours. The reaction mixture was quenched carefully with 3N HCl and then extracted with EtOAc (3×10 mL). The organic layers were combined, washed with brine, dried (MgSO4), filtered and concentrated to yield the desired product.
