clear colourless to light yellow liquid | [Uses]
Methyl 4-(Chloroformyl)butyrate is used in the synthesis of Leukotriene B4, a proinflammatory agent produced from leukocytes. | [Synthesis]
1. 100 g (0.878 mol) of glutaric anhydride was dissolved in 50 mL of anhydrous methanol and heated to reflux for 1 h. 2. Upon completion of the reaction, unreacted methanol was removed by distillation under reduced pressure. 3. The reaction mixture was cooled to room temperature, and 200 mL of acetochloride was slowly added. 4. The reaction mixture was heated for 6 h., wherein after 2 h of heating the remaining dichloro sulfoxide.5. Finally, the fractions were dried at 96 °C to 98 °C/10 mmHg to give 124.2 g of methyl 4-chlorocarbonylbutyrate as a light yellow liquid in 86.4% yield. | [References]
