Reaction Steps

To a solution of 4-amino-3-(methylthio)benzonitrile (71.1 mg) and 5N aqueous hydrochloric acid (2.0 ml)/ethanol (0.5 ml) was added under ice cooling sodium nitrite (32.5 mg) and the resulting mixture was stirred for one and a half hours. To the reaction mixture was added tin(II) chloride (101.4 mg) and the resulting mixture was stirred at 0° C. for two and a half hours. The reaction mixture was filtered, and the mother liquor was basified (pH=about 10) with potassium carbonate and extracted with chloroform (30 ml) three times, and the organic layer was dried over sodium sulfate and then concentrated under reduced pressure to afford 4-hydrazinyl-3-(methylthio)benzonitrile (57.7 mg).
