化学合成

路线1：

• 原料：1-(3,4-二甲氧基苯基)乙酮（1.0g，5.55mmol）、苄基三甲基三溴化铵（2.16g，5.55mmol）
• 溶剂：二氯甲烷（6mL）、甲醇（3mL）
• 步骤：向搅拌的1-(3,4-二甲氧基苯基)乙酮的二氯甲烷和甲醇混合溶液中加入苄基三甲基三溴化铵，16小时后，用二氯甲烷（80mL）和水（40mL）稀释，分离有机层，水相用二氯甲烷（80mL×2）萃取，合并有机相，无水硫酸钠干燥，过滤并浓缩，得到产物
• 收率：83%（1.20g，4.63mmol）
• 表征：1H NMR（400MHz，CDCl3）：δ 7.63（s，1H），7.57（d，J=2.1Hz，1H），6.94（d，J=8.4Hz，1H），4.43（s，2H），3.98（s，6H）
