130 BIBLIOGRAPHY OF 



imidomethyluracyl is heated with an excess of methyl iodid a com- 

 pound, (C5 He N3O 01^3)2 HI , is obtained, which melts at 212° and can 

 be converted into methyl-imidomethyl-uracyl, C5 He N3 OCH3 , which 

 melts at 312.° Imidodimethyluracyl formed from giianidin carbonate 

 and methyl-acetoacetic ester melts at 320', and imido-phenyl-uracyl 

 formed from guanidin carbonate and benzoylacetic ester melts at 294.°

 Action of Sodacetoacetic Ester on Benzalmalonic Ester. 



By this reaction in alcoholic solution at o a crystalline sodium 

 compound is formed which when decomposed by an acid gives a 

 compound C18 H20 Oe , which is sparingly soluble in water and melts 

 with decomposition at 155°

Action of Sodium Phenylmercaptid on Chloracetoacetic Ester. 



When equivalent quantities of these substances are made to react in 

 alcoholic solutions, an oil is obtained, which will not crystallize and 

 has but a feeble odor. It appears to be thiophenylacetoacetic ester, 

 CH3 COCH (SCe H5 ) CO2 C2 H5 .
