YieldReaction ConditionsOperation in experiment
90% With XtalFluor-E; triethylamine tris(hydrogen fluoride); In dichloromethane; at 20℃; To triethylamine trihydrofluoride (1.956 mL, 12.00 mmol) in DCM (18 mL) at RT were added successively XtalFluor-E (2.061 g, 9.00 mmol) and pyrazine-2-carbaldehyde (0.649 g, 6 mmol). The reaction mixture was stirred overnight at RT. The reaction mixture was quenched with sat. NaHCO3 solution and next extracted with DCM (3x 50 mL), dried (MgSO4) and evaporated under reduced pressure. The product was purified by flash chromatography (100percent DCM) yielding the title compound as a clear oil (703 mg, 90percent).LCMS (Method C): RT = 0.58 mi mlz = 131 [M+H].1H NMR (500 MHz, CDCI3) O 8.95 (s, 1H), 8.74 (s, 1H), 8.65 (s, 1H), 6.71 (t, J 54.7 Hz, 1H)
