4-ethoxy-3,3-dimethyl-4-oxobutanoic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 3-ethoxycarbonyl-3,3-dimethylpropionic acid (1 g) and 3 ml of thionyl chloride was stirred at room temperature for 20 hours. The excess thionyl chloride was removed in vacuo to afford 1.1 g of 3-ethoxycarbonyl-3,3-dimethylpropionyl chloride. The excess thionyl chloride was removed in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
