YieldReaction ConditionsOperation in experiment
With pyridinium p-toluenesulfonate; In acetonitrile; for 72h;Heating / reflux; Step 2 5 ,8-Diotabromo-3-methyliotamiotadazo[ 1 ,2 ajpyrazine[00298] 2,5-Dibromo-3-aminopyrazme (2 0 g, 7 9 mmol), 2-bromo-l,l -dimethoxypropane (7 25 g, 40 0 mmol) and py?dimum p-toluenesulfonate (2 0 g, 7 9 mmol) are stirred in acetomtrile (65 mL) at reflux for 3 days The mixture is cooled and the solvent evaporated under reduced pressure The residue is partitioned between DCM (150 mL) and water (50 mL) and the layers separated The organic fraction is washed with NaHCtheta3 (sat aq , 50 mL) and b?ne (50 mL) and d?ed over MgStheta4 Evaporation of the solvent under reduced pressure gives a viscous black oil (2 14 g) which is purified by silica chromatography, elutmg with 10% - 20% EtOAc in cyclohexane to afford the title compound as a red-brown solid (280 mg, 1 mmol)
