Reaction Steps

After 6-hydroxy-1-tetralone 1.0 g and 4-dimethylaminobenzaldehyde 0.97 g were added to a mixture of concentrated hydrochloric acid 50 ml and methanol 75 ml, the mixture was refluxed for 1.5 hours and cooled to room temperature, and water 400 ml was added. The precipitated crystals were filtered. The crystals were dried over phosphorous pentoxide for six hours under reduced pressure to obtain the desired compound 0.885 g.
