22766-68-3,Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials.22766-68-3,A new synthetic method of this compound is introduced below.
Example 33 Preparation of 1-azabicyclo[2.2.2]oct-4-yl(di-3-thienyl)methanol A solution of t-Butyl lithium (1.7M in pentanes, 5.8 mL, 9.86 mmol) was chilled to -78 C. under Ar. 3-Bromothiophene (0.46 mL, 4.90 mmol) dissolved in THF (4.0 mL) was slowly added to the reaction mixture over 6 min. The reaction was stirred for 30 min and then ethyl 1-azabicyclo[2.2.2]octane-4-carboxylate (0.3132 g, 1.71 mmol) in THF (4 mL) was added. The reaction was allowed to warm up from -78 C. to room temperature over 16 h. After 14 hours, the reaction was slowly quenched with water. EtOAc was added, causing a grey solid to crash out. The solid was filtered off to give the title compound (0.3375 g, 64.6%). EI-MS m/z 306(M+H)+ Rt (1.27 min).
