Benzonitrile, 4-hydrazinyl-, hydrochloride (1:1) Use and Manufacturing
To a cooled (−5 to 0°C) stirred suspension of 4-aminobenzonitrile (50g, 423mmol) in concentrated hydrochloric acid (550mL) was added dropwise aqueous sodium nitrite solution (31.5g, 457mmol in 200mL water). To this diazotised solution cooled (0°C) solution of tin (II) chloride dihydrate (477g, 2.1mol) in concentrated hydrochloric acid (370mL) was added while stirring and maintaining the temperature below 0°C. The resulting solution was further stirred for 15min. White precipitates so formed were collected by filtration, washed with diethylether and crystallized from aqueous ethanol. Mp 234–236°C (Lit. mp 235–237°C), yield 60g (84percent).
