YieldReaction ConditionsOperation in experiment
With potassium carbonate; In acetonitrile; at 70℃; To the jacketed reactor was charged acetonitrile (157 g) and potassium carbonate (179 g, 1280 mmol) and the temperature was brought to about 70 C. The crude methyl 2,3- dibromobutanoate was added to the reactor over a 4-h period with vigorous stirring. The slurry changed from dark red to yellow-orange. The reaction mixture was stirred at about 70 C until GC analysis showed methyl-2, 3 -dibromobutanoate to be less than 0.3% by GC area. The reaction was not worked up but used as the resulting slurry in Step 2. If worked up by filtration, washing of the filter cake with acetonitrile and evaporation of volatiles, the crude methyl-2-bromocrotonate can be obtained as an oil. Expected yield is greater than 97% with a purity of about 95%.
