Reaction Steps

Benzamidine hydrochloride and an equimolar amount of sodium methylate were heated under reflux in tetrahydrofuran for 1 hour. After cooling, a tetrahydrofuran solution of an equimolar amount of ω-bromo-2-acetonaphthone was added dropwise thereto so that the temperature did not exceed 30° C., and then an equimolar amount of sodium methylate was further added, followed by heating under reflux for 1 hour. After removal of the solvent by distillation under reduced pressure, the residue was washed with water and subjected to recrystallization from acetonitrile to obtain grayish blue crystals.
