Reaction Steps

84 ml of oxalyl chloride in 800 ml of ether was cooled to -60° C. and over half-an-hour, a solution of 94 ml of tert.-butanol, 80 ml of pyridine and 200 ml of ether was added. The temperature was allowed to rise to 0° C. with stirring for a further hour. After filtering and concentrating the filtrate dryness, the residue was distilled under reduced pressure to obtain 93 g of tert-butyloxalic acid chloride boiling at 13 mm Hg, 45°-46° C.
