An investigation of the reduction products of 4-amino-2, 6-dichloropyrimidine by catalytic hydrogenation

Creator:: Leutzinger, Eldon Edward
Abstract:: In recent years nuclear reduction of pyrimidines by catalytic hydrogenation in acid media has been considered a possible synthetic method for the preparation of substituted tetrahydropyrimidines. This technique has the advantage of simplicity over the older condensation methods and is limited only by the preparation of the appropriately substituted pyrimidines....

The chlorination of uric acid by phosphorus oxychloride in the presence of certain aliphatic and aromatic amine hydrochlorides

Creator:: Haase, William Alan
Abstract:: Since the use of N, N-diethylaniline hydrochloride in the chlorination of uric acid with phosphoryl chloride seems to promote the reaction, a study of the effect of other salts of nitrogenous bases in the chlorination of uric acid was undertaken. When N, N-diethylaniline hydrochloride was used in lieu of the...

The study of the influence of the nitro substituent on the hydrazinolysis of certain substituted 5-nitropyrimidines

Creator:: Stahl, Quade Russell
Abstract:: The unique reaction between 4, 6-dimethoxy-5-nitropyrimidine and methylhydrazine was investigated. The reaction product was identified as 4-hydrazino-6-hydroxypyrimidine from (a) spectral data, (b) by direct synthesis of the product via 4-chloro-6-hydroxypyrimidine and hydrazine, and (c) by conversion of the product to the known 4-amino-6-hydroxypyrimidine using Raney nickel. The product was not...

A study of the limitations of ultraviolet spectral data for the determination of dissociation constants of organic nitrogeneous bases

Creator:: Vachananda, Sookapracha
Abstract:: Ultraviolet spectroscopic methods for the determination of dissociation constants can only be applied to those compounds having protonatable sites conjugated with or inherent in a chromophoric group of the compound. The determination of the dissociation constants of organic nitrogeneous bases by ultraviolet spectroscopic methods was found to be only reliable...

A study of certain reactions of 4-chloro-6-methylhydrazino-5-nitropyrimidine and the 4-methoxy and 6-dimethylamino analogs

Creator:: Tantivanich, Amnard
Abstract:: The reaction between 4- chloro- 6- methoxy- 5-nitropyrimidine and methylamine was investigated. The reaction product was identified as 4-methoxy-6-methylamino-5-nitropyrimidine from synthesis of the product via 4-chloro-6-methylamino-5-nitropyrimidine. The product was the result of displacement of chloro substituent with methylamine. The reaction occured under mild condition (e. g. 15-20 C. in dioxane)....

A study of the permanganate oxidation of 4-methylpyrimidine to pyrimidine-4-carboxylic acid

Creator:: Ni, Rain Wo
Abstract:: The yields from the oxidation of 4-methylpyrimidine with potassium permanganate were found to increase from 25 to 92 percent by the addition of small amount of potassium hydroxide to the reaction mixture. Pyrimidine-4-carboxylic acid decarboxylates in hot aqueous solution to yield pyrimidine and carbon dioxide. The rate is that decarboxylation...
