37. 6 (2 mL) was added. The mixture solution was stirred at 75 °C for 35 min. The progress of the reaction was monitored by TLC. After completion of the reaction, the reaction was cooled to room temperature and the crude product was extracted with ethyl acetate (3 × 10 mL). The extracted solution was dried over anhydrous magnesium sulfate and concentrated in vacuo. The crude product 3a was purified by recrystallization from ethanol.
