Reaction Steps

A mixture of 1,2,3,4-tetrahydronaphthalen-2-one (3.5 g, 24.0 mmol) and formic hydrazide (1.56 g, 26.0 mmol) in 25 mL of ethanol and 1 drop of concentrated hydrochloric acid was heated at 70° C. for 1 hour. The mixture was cooled to room temperature giving a crystalline material. The material was isolated by filtration and washed with ethanol. Drying gave 2-formylhydrazono-1,2,3,4-tetrahydronaphthalene (3.5 g, 8.7 mmol).
