Reaction Steps
First, 71.2 mmol of 2-chlorobenzonitrile was dissolved in 50 ml of methanol, and 356 mmol of hydrazine and 35.6 mmol of 28% methylate were added thereto, followed by keeping at the reflux temperature for 5 hours. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in 50 ml of 50% hydrochloric acid, and 74.8 mmol of sodium nitrite was added thereto at 0C to cause reaction. The reaction mixture was extracted with ethyl acetate to give 5-(2-chlorophenyl)tetrazole. Yield, 70%.
