실험 절차

3,4-Dicyano-benzoic acid methyl ester from step 1 (2.4 g, 12.9 mmol ) was dissolved in THF (65 ml). LiBH4 in THF (2 M, 12.9 ml, 25.8 mmol) was added. The reaction mixture was heated to 70° C. for 3 hours. The reaction was quenched carefully with 3N HCl and then extracted with EtOAc (3×20 mL). The organic layers were combined, washed with brine, dried (MgSO4), filtered and concentrated to yield the desired product.
