78% | With hydrazine hydrate In (2S)-N-methyl-1-phenylpropan-2-amine hydrate | Step 4 A portion of 2-chloro-4-nitrobenzonitrile (5 g, 0.027 m) was heated with hydrazine monohydrate (110 ml) until the reaction began. Another portion of 2-chloro-4-nitrobenzonitrile (35 g, 0.192 m) was added in predetermined amounts. Once the evolution of nitrogen gas ceased, the reaction mixture was refluxed approximately thirty minutes, and then poured into stirred ice water. The precipitate was filtered and the solid was crystallized from water to yield 2-chloro-4-aminobenzonitrile (25 g, 78percent, mp 117° C.). |
