170 Mr Hill, A Series of Substituted Bromanilines. 
well from alcohol, in which it was only slightly soluble. It melted 
at 136°— 137° C. 
The quaternary hydroxide obtained from the methyl iodide 
compound, on decomposition, gave back methyKsobutylbromani- 
line. 
Methylisoamylbromaniline. 
It was prepared in a similar way to the others. It distilled 
at 165°— 170° C. at 5 mms. 
The quaternary iodide came down readily on adding methyl 
iodide and crystallised well from alcohol. Melting point 176° C. 
The picrate was only obtained in crystalline form with diffi- 
culty. After recrystallising from alcohol its melting point became 
constant at 89° C. 
The quaternary hydroxide, obtained from the methyl iodide 
compound, decomposed on heating to give back methyh’soamyl- 
bromaniline. 
It will thus be seen that all these quaternary hydroxides, 
except that of methylethylbromaniline, split off a methyl group, 
on heating, and give back the original base. 
In conclusion, I wish to express my thanks to Mr H. O. Jones 
for suggesting this work and for his kind advice during the course 
of it.
