The solution was heated at a temperature of 60° C, then 3.1 g of dimethyl sulfate was added dropwise to the solution with stirring and the mixture was allowed to react for 1.5 hours. The reaction mixture was poured into an appropriate amount of water, and the mixture was extracted with diethyl ether. The extract was washed with water and dried over anhydrous sodium sulfate, and the ether was removed by distillation. The residue was distilled under reduced pressure to obtain 3.0 g of the desired product having a boiling point of 182° to 185° C/1.5 mmHg.
