Route of Synthesis (ROS)
| Conditions | Yield |
| With lithium aluminium hydride In tetrahydrofuran at 20℃; Experimental Procedure 1.5-1 Step 5-1: Synthesis of e1: In a 250mL flask, weigh e0 (5.00g) and dissolve it in 100mL of THF, add LiAlH4 (2.0eq) under an ice bath, and then warm to room temperature to react overnight;The progress of the reaction is monitored by the dot plate, and the reaction is completely post-processed;The reaction solution was poured into 300 mL of ice water, stirred, suction filtered, washed with water, dried, and dried to obtain a bright yellow solid (3.2 g, 87.7% yield). The hydrogen spectrum of the compound is shown in Figure 8. | 87.7% |
