Ryan and Egan — Condensation of Nitrosophenylurethane^ Sfc. 333 



The neutral substance, which was readily soluble in ether, was separated 

 from the indamine hydrochloride by means of this solvent. It was dissolved 

 in hot alcohol, from which it separated on cooling as acicular prisms, which 

 melted at 212^ C, and gave on analysis the following results : — 



0"1039 g. substance gave 14'6 c.c. moist N" at 16° 0. and 754 m.m., 

 corresponding to N 16-25. 



The percentage of nitrogen corresponds approximately to that required 

 for the hydrochloride of an indamine from nitrosophenylurethane and 

 m-toluyleuediamiue. The colour of- the substance was too light for the 

 hydrochloride of an indamine, and, moreover, the body was not a hydrochloride. 

 The same substance was formed when toluylenediamine was replaced by 

 a-naphthylamine in the reaction. Since, therefore, it was not a condensation 

 derivative of the base, it was not further examined.
