The reaction between isatiu and y. benzyl hydroxylamine takes 

 place already in the cold. In order to complète it, however, we heated 

 the ingrédients just as .stated in the foregoing example in a sealed 

 tube for 2 hours. The purification of the benzylether bas bcen 

 carried out exactly as stated in the case of isatinoxime benzylether.
