Reaction Steps

74 g of t-butylalcohol, 79 g of pyridine and 250 ml of anhydrous ether were heated to boiling and 146 g of dichloroacetyl chloride were added dropwise to the reaction mixture at such a rate that the mixture continued to boil without further supply of heat. When all the dichloroacetyl chloride has been added, boiling was continued for 3 hours. Water was then added to the reaction mixture and the ethereal phase was separated off. The resulting reaction solution was processed in the usual manner to yield 140 g of α, α-dichloroacetic acid-t-butyl ester.
