Chloral and p-Bromaniline. 
Irichlorethylidenedi-p-bromfihenamine, 
CCl 3 CH(NHBrC 6 H 4 ) 3 . 
With C. W. Miller. Ten grams of p-bromaniline were dis- 
solved in 50cc benzene and 8 grams of chloral (4.2 grams 
required by theory) in lOcc benzene were added. The mix- 
ture was concentrated one-half on the water bath and cooled. 
A white flocculent precipitate came down. This gave a 
melting point of 135°. On further evaporation a second crop 
was obtained, showing a melting point of 119°. By several 
recrystallizations from benzene the melting point was raised 
to 140°. The yield of the crude product was quantitative. 
Analysis: 
0.1588g substance gave 0.2049g C0 2 and 0.0352g H a O. 
0.1638g substance gave 9cc nitrogen at 15° and 755mm. 
0.0890 substance heated with 0.3274g AgN0 3 required 
9.8cc NH 4 SCN (lcc = 0.0l73g AgN0 3 ).

Trichlorethylidenedi-p-bromphenamine consists of fine col- 
orless needles, melting at 140° and decomposing at 205° . It 
is extremely soluble in alcohol, acetone, glacial acetic acid 
and hot benzene. It is sparingly soluble in cold benzene and 
insoluble in ligroin. It is readily purified by using a mixture 
of benzene and ligroin. It is not decomposed by boiling 
water but is split by boiling concentrated hydrochloric acid 
with the regeneration of p-bromaniline. A bromo derivative 
is easily obtained by adding bromine to a glacial acetic acid 
solution. The product, consisting of plates, melts at 203°
