39% | 2-Methoxybenzonitrile (3.0 g, 22.5 mmol) and 2-methylpyrazine (2.2 g, 23.0 mmol) were dissolved in an ice-water bathIn dry tetrahydrofuran (50 mL) and stirred under nitrogen for 1.5 hours.under this conditionLithium diisopropylamide (23 mL, 45.06 mmol, tetrahydrofuran solution) was slowly added, and the addition was complete and the temperature was raised to 40C and stirring was continued for 3 hours.The reaction solution was cooled to ambient temperature, quenched with ammonium chloride solution, extracted with ethyl acetate (50 mL × 3), dried over anhydrous sodium sulfate, and filtered.The organic layer was concentrated under reduced pressure and the residue was purified by flash column chromatography (petroleum ether/ethyl acetate = 1/1) to give compound 5.1 as a yellow solid.Body (2.2 g, yield: 39%). |
