Versuchsvorschrift

The chloride of 4-nitrophenylacetic acid in solution in dry acetone (7.5 ml) is slowly added to an aqueous solution of 0.75 g (11.5 mmoles) of sodium azide, cooled down to 0° C. Agitation of the medium is maintained for one hour after the addition is completed, at 0-5° C. The reaction medium is then diluted with 30 ml of chloroform, decanted and the organic phase washed with water (20 ml) followed by a saturated solution of sodium chloride (20 ml). After drying over sodium sulphate, the organic solution is filtered and partly concentrated (* 20 ml) under vacuum.
