合成路线 1（1. 合成：20668-20-6）
产率：93%
合成条件：With iron(II) triflate; C 13 H 21 N 3 O 2 In chloroform at 40℃; for 2 h; Schlenk technique
实验步骤：一般步骤：在10mL Schlenk管中，加入Fe（OTf）2（0.005mmol，1.8mg），喹啉（0.5mmol，72mg），Hantzsch酯A（1.25mmol，318mg）和1.0mL CHCl 3。 将混合物在40℃下搅拌2小时。 将溶液减压浓缩。 通过硅胶柱色谱法纯化粗产物，得到纯的1,2,3,4-四氢喹啉（63.8mg，96％收率）。
