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

 Phenyl-brom-acetic Acid on Acetoacetic Ester. 



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

 results were obtained. Aceto-phenon bromid, Ce H 5 COCH 2 Br, acting 

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

 when treated with sodium amalgam becomes a hydroxylactone, 



CH 3 CHOHCH<Q 2 > CHC 6 H 5 . Phenyl-brom-acetic ester and 

 acetoacetic ester produce phenyl-aceto-succinic ester,

CO C 6 H 5 ; from this the ketone acid, CO C 6 H 5 ,

 Acetyl-^-imidobutyric Ester. 



By heating acetoacetic ester with acetamid and aluminum chlorid 

 under reduced pressure there is produced acetyl-/9-imidobutyric ester 

 which melts at 64 to 65? Its formula is 



CH 3 CO N = C (CH 3 ) CH 2 CO 2 C 2 H 5 .
