One of the major reasons is to use measurements of the macroscopic properties of a system, the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level. 22766-68-3, introduce a new downstream synthesis route., 22766-68-322766-68-3
Example 27 Preparation of 1-azabicyclo[2.2.2]oct-4-yl(di-2-thienyl)methanol A solution of 2-thienyllithium (1.0M in THF, 9.10 mL, 9.10 mmol) was chilled down to -30 C. under Ar. Ethyl 1-azabicyclo[2.2.2]octane-4-carboxylate (0.4196 g, 2.289 mmol) in THF (8 mL) was slowly added to the reaction mixture over 20 min. The reaction was allowed to warm up to room temperature over 16 h. The reaction was quenched with water and then evaporated to dryness. H2O and DCM were added, causing a light brown solid to crash out. This solid was filtered off to give the title compound (0.4161 g, 59.5%). EI-MS m/z 306(M+H+) Rt (1.35 min).
