    • The method in accordance with the present invention has: mixing E2M, an organic solvent, a weak base, sodium dithionite, and a phase transfer catalyst to obtain an E2M mixture solution; heating the E2M mixture solution and adding water to obtain a heated E2M aqueous solution having an organic layer; and extracting the organic layer from the heated E2M aqueous solution, and condensing and drying the organic layer to obtain donepezil. Employing sodium dithionite as a reducing agent improves safety over hydrogen gas used in conventional methods and lowers the cost in contrast to the conventional noble metal catalysts that are extremely expensive. Furthermore, the method of the present invention requires only 60 minutes of reaction time to synthesize donepezil with a promising yield more than 85%, which greatly raises the efficiency and economic value of the manufacture of donepezil.
    • 根据本发明的方法具有:混合E2M,有机溶剂,弱碱,连二亚硫酸钠和相转移催化剂,得到E2M混合溶液; 加热E2M混合溶液并加水,得到具有有机层的加热的E2M水溶液; 从加热的E2M水溶液中萃取有机层,冷凝干燥有机层得到多奈哌齐。 使用连二亚硫酸钠作为还原剂提高了与常规方法中使用的氢气相比的安全性,并且降低了与常规贵金属催化剂相当昂贵的成本。 此外,本发明的方法仅需60分钟的反应时间合成多奈哌齐,产率高达85%以上,大大提高了多奈哌齐的制造效率和经济价值。
