Reaction Steps
10.0 g (57 mmol) of 6-methoxy-1-tetralone in 125 ml of ethanol is added in drops within 35 minutes to a boiling solution of 10.0 g (57 mmol) of p-methoxyphenylhydrazine-hydrochloride and 5.0 ml of concentrated hydrochloric acid in 180 ml of ethanol. Then, it is refluxed for 5 hours. After 370 ml of hot water is added, it is allowed to cool. The almost colorless reaction product is suctioned off and recrystallized from ethanol. Yield 74%, melting point 189-191° C.
