Procedure
60.0 ml of oxalyl chloride are added to a solution of 98.73 g of 6-oxaspiro[2.5]-octane-1-carboxylic acid in 500 ml of dichloromethane at 0° C. One drop of N,N-dimethylformamide is added, and the reaction solution is stirred at room temperature for 1 hour. The reaction solution is then evaporated, and the crude product is employed directly for the next stage.
