Participants

Reaction Steps

A mixture of 10.0 g of 6,7-dimethyl-α-tetralone, 6.0 g of dimethyl amine hydrochloride, 2.2 g of paraformaldehyde, and 12 ml of 95% ethanol containing .15 ml of concentrated hydrogen chloride is heated on a steam bath for 3 hours. After the mixture has been heating for a short time, an additional 20 ml of 95% ethanol is added. The mixture is cooled, yielding a crystalline mass that is washed with absolute ethanol to give 11.5 g of the title compound, melting point 204°-205° C.
