With zinc perchlorate; In neat (no solvent); at 50℃; for 5h;
General procedure: A mixture of nitrile (5 mmol), tert-butyl benzoate (5.5 mmol) and Zn(ClO4)2·6H2O (2 mol%) was placed in around bottom flask. Then, the reaction mixture was heated at 50 C for the given time. After completion of the reaction monitored by thin layer chromatography (TLC), the reaction mixture was quenched with 5-ml water. Then the reaction system was added 10 ml aqueous NaOH solution (1 mol/L) and continued to be stirred 5 min and extracted with ethyl acetate (3 × 10 ml). The organic layers were collected, combined, washed with water (3 × 10 ml), driedover anhydrous Na2SO4, and concentrated under vacuum.
