A study of factors leading to N, N-diacetylation of aminopyrimidines

Creator:: Carson, Bonnie L.
Abstract:: Although 4- and 5-diacetamidopyrimidines have been reported in the literature within the past eleven years, it was not until 1965 that a 2-diacetamidopyrimidine was reported. The current investigation was undertaken to determine whether other 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...

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)....

The investigations of the methods for the reduction of chloropyrimidines

Creator:: Ladpli, Vimolvan
Abstract:: This thesis investigated on the dehalogenation of 2, 4- dichloropyrimidine in various different conditions. These conditions were changed by varying the solvents, the amount of catalysts and the hydrogen chloride acceptors in order to study the effects on the yields. It was found that the ether-aqueous sodium hydroxide medium with...

A study of certain novel reactions of 4,6-dimethoxy-5-nitropyrimidine

Creator:: Harper, Richard Waltz
Abstract:: Reaction of 4, 6-dimethoxy-5-nitropyrimidine [I], with refluxing pyridine, was discovered to yield the methylpyridinium salt of 1, 6-dihydr -4-hydroxy-1-methyl-5-nitro-6-oxopyrimidine [III]. Possible use of I as a general N-methylating agent was explored. No appreciable reaction occurred between I and refluxing excess n-butyl alcohol. Similar reaction involving quinoline failed to yield an...
