실험 절차

4-Formyl-3-methoxymethoxy-N-(1-methyl-1-phenylethyl)benzamide (3.12 g, 9.53 mmol) was dissolved in methanol (30 mL), and the solution was added with trimethyl orthoformate (2.09 mL, 19.1 mmol) and p-toluenesulfonic acid monohydrate (16.4 mg, 0.0952 mmol), followed by stirring at room temperature for 1 hour. The reaction mixture was added with saturated aqueous sodium hydrogencarbonate solution and water, and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to obtain 3-methoxymethoxy-4-dimethoxymethyl-N-(1-methyl-1-phenylethyl)benzamide (3.61 g, yield 100%).
