Reaction Steps

Oxalyl chloride (1.0 kg) was added to a solution of 1-(4-fluoro-phenylcarbamoyl)-cyclopropanecarboxylic acid (2.0 kg) in a mixture of THF (11 kg) and N,N-dimethylformamide (DMF; 0.02 kg) at a rate such that the batch temperature did not exceed 30° C. This solution was used in the next step without further processing.
