That the transformation is not, however, limited to carbamide 

 derivatives, is shown by the following case. 



Dimethjloxanilide, C20,[N(CH,)(CgH5)],, was heated with aniline 

 hydrochloride. On treatment in the manner described above, a product 

 was formed which melted at 245° C. This melting point agrees 

 with that of oxanilide C,0,(NH . C„HJ,. Mixed with the latter 

 substance there was no depression of the melting point, so that we 

 have here another example of the replacement of the group 

 — CO . N(CH3)(C,H J by the group — CO . NH . C,H,. 



Investigations in this direction are being continued with other 

 aromatic amines.
