Versuchsvorschrift

13.7 g of p-aminobenzoic acid was dispersed in a solution of 100 cc of water and 30 cc of 30% hydrochloric acid in an ordinary manner and the dispersion was cooled with ice. A solution of 8.3 g of sodium nitrite in 50 cc of water was added dropwise to the dispersion to effect the diazotization reaction. A solution of 10.1 g of sodium azide in 70 cc of water was added dropwise to the mixture, stirred for about one hour, filtered and vacuum-dried to obtain p-azidobenzoic acid. 5.4 g of the thus obtained p-azidobenzoic acid was dissolved in 10 cc of dimethylformamide and 25 g of thionyl chloride was added dropwise to the solution. The mixture was stirred for about one hour and the product was added dropwise to ice-water. After filtration followed by washing with water and vacuum drying, p-azidobenzoyl chloride was obtained.
