(Step 1) To a solution of 2-amino-5-chlorobenzonitrile (5.0 g) and dimethylaminopyridine (0.12 g) in dimethylacetamide (25 ml) was added dropwise phenyl chlorocarbonate (6.2 ml) at room temperature, and the mixture was stirred overnight. The reaction mixture was poured into water, and extracted twice with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:5-*3:7) to give phenyl (4-chloro-2-cyanophenyl)carbamate (7.04 g).
