English term or phrase:CV
The mixtures were allowed to stir at RT for 2 hours at which time LC-MS showed completed conversion. Quenched with 10ml 1N HCl. The mixtures were poured into 250ml of EtOAc, washed with 10% LiCl twice, Brine once. The organic layer was then dried over Na2SO4 and concentrated. The crude materials were purified by RediSep Column: Silica 220g
Flow Rate: 150 ml/min
Equilibration Volume: 1.0 ***CV***
Solvent: A1 hexane; Solvent: B1 ethyl acetate
Gradient 0%--40% Sol B in 15mins.
Fractions containing the desired product were combined and dried via centrifugal evaporation to provide the title compound (1.86g, 65%).
Analysis LCMS Condition A: Retention time = 1.14 min; ESI-MS(+) m/z 477.1 (M+H).
