실험 절차

The reaction was performed as in Example 1. The following reactants were charged to the reactor: 2,4-DCBTC (132.8 g, 0.5 mol), ammonium chloride (28.1 g, 1.05 eq), and 2,4-dichlorobenzoyl chloride (13.3 g). The mixture was heated at 230° C. for 14 h. Distillation of the reaction mixture gave pure 2,4-dichlorobenzonitrile (2,4-DCBN) (76.4 g, 89% yield, melting point: 59°-60° C.).
