Action of Chlor= and Brom=acetone, Aceto=phenon Bromid and 

 PhenyI=brom=acetic Acid on Acetoacetic Ester. 



Chlor- and Brom-acetone act on acetoacetic ester but no definite 

 results were obtained. Aceto-plienon bromid, Ce H5 COCH2 Br, acting 

 on acetoacetic ester produces aceto-phenon-acetoacetic ester, which, 

 when treated with sodium amalgam becomes a hydroxylactone, 



CH3CH0HCH<^q'> CHCsHs. Phenyl-brom-acetic ester and 



acetoacetic ester produce phenyl-aceto-succinic ester.

Acetyl=9=imidobutyric Ester. 



B}^ heating acetoacetic ester with acetamid and aluminum chlorid 

 under reduced pressure there is produced acetjd-^J-imidobutyric ester 

 which melts at 64° to 65.° Its formula is 



CH3 CO — N = C (CH3 ) CH, CO. C. H5 .
