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
A solution of phenyllithium (1 .9 M in 70 cyclohexane/30 ether, 22.30 mL, 42.40 mmol) was cooled down to -30C under nitrogen. A solution of ethyl 1 -azabicyclo[2.2.2]octane-4-carboxylate (III, 2.0 g, 10.90 mmol) in THF (27.0 mL) was slowly added to the reaction mixture at -30C over 25 mins. The reaction mixture was allowed to warm up to room temperature over 16h. The reaction was quenched with water (10.0 mL) and then evaporated to dryness under vacuum. Water (40.0 mL) and ethyl acetate (40.0 mL) were added, causing a white solid to crash out. This solid was filtered off under vacuum, to give a white powder (2.46 g, 76.8%). 1 -azabicyclo[2.2.2]oct-4-yl(diphenyl)methanol (IV): ^H-NMR (300 MHz, CDC ) delta 7.54 – 7.51 (m, 3H), 7.33 – 7.20 (m, 6H), 2.85 – 2.80 (m, 6H), 1 .78 – 1.72 (m, 6H). MS (ESI) m/z calcd for C20H23NO: 293, found 294 [M + H]+.
