Reaction Steps
A solution of sodium nitrite (4.0 g) in water (7 ml) was added to an ice cooled mixture of 3-cyano-4-methoxyaniline (7.7 g) and concentrated hydrochloric acid (21 ml). The mixture was stirred at 0° C. for 30 minutes. To the resultant mixture a solution of tin(II) chloride dihydrate (49 g) and concentrated hydrochloric acid (5 ml) was added at 0° C. and stirred for 1 hour. The precipitates were filtered and washed with ice cooled concentrated hydrochloric acid (10 ml) to give crude (3-cyano-4-methoxyphenyl)hydrazine hydrochloride (14.8 g).
