15.0 grams (61.3 mmoles) of the 2-chloro-3-benzylmercapto-propionic acid methyl ester produced in Example 3 were stirred with 5.98 grams (92.0 mmoles) of sodium azide and 1.5 grams of Aliquat 336 in 30 ml of water for 7 hours at 45° C. After working up according to Example 2 there were obtained 15.2 grams (99% of theory) of 2-azido-3-benzylmercapto-propionic acid methyl ester.
