Versuchsvorschrift

To a suspension of 4.565 g (20 mmol) 4-benzyloxybenzoic acid in 25 ml THF and 0.3 ml N,N-dimethylformamide was added dropwise at 0° C. a solution of 2.6 ml oxalyl chloride in 5 ml THF. Stirring was continued for 3 hours at room temperature, then the suspension was added slowly to a stirred ice-cold solution of concentrated aqueous ammonia. The organic solvent was evaporated, 100 ml water added and the precipitate isolated and dried in vacuo at 50° C. Yield: 4.29 g (94%) white solid.
