is formed, a pale yellow liquid boiling at 245 to 247 By repeating 

 former experiments with acetoacetic ester and formamid, a liquid boil- 

 ing at 250 to 255 was obtained which was mono-lutidin-carboxylic 

 ester and which apparently is isomeric with Michael's body of the same 

 name which he obtained from aldehyde, aldehyde ammonia and 

 acetoacetic ester.

 Action of Acetoacetic Ester on Hydrazo-benzene. 



When acetoacetic ester is treated with hydrazo-benzene, C& H 5 

 NH NHC 6 H 5 , a compound C l6 H I4 N 2 O. which melts at 120 and 

 is weakly basic and acid is formed. It is probably a phenylated

By treating a mixture of two molecules phenyl mercaptan and one
