Reaction Steps
A mixture of 43.2 g (0.4 mol) of o-cresol and 17.1 g (0.1 mol) of β-acetonaphthone was made into a solution by heating at about 30° C. After adding 0.1 ml of sulfuric acid, 0.8 ml of 3-mercaptopropionic acid and 10 ml of toluene to the solution, the reaction was allowed to proceed under stirring. After confirming that the conversion reached 100% by a gas chromatographic analysis, 100 ml of toluene was added. The solid precipitated by cooling was filtered under reduced pressure, washed with a warm water of 60° C. under stirring, and purified by a silica gel column chromatography, to obtain 24 g of the title compound.
