PROCESS FOR THE PRODUCTION OF PYRIMIDINE-5-CARBOXYLATES

Pyrimidine-5-carboxylates of formula wherein R is C1-4 alkyl, R1 is C1_4 alkyl or trifluoromethyl, R2 is hydrogen or C1 alkyl and X is hydroxy, chlorine or bromine, are prepared from 3-oxoalkanoates of formula with urea and orthoesters of formula R2C(OR)3 (III). The intermediate 2-acyl-3-ureidoacrylate, without being isolated, is reacted to give a 2-hydroxypyrimidine-5-carboxylate [(I), X = OH] or a hydrate thereof, which is optionally converted into the corresponding chloro or bromo compound (I, X = Cl, Br).

Structure-activity relationship studies of ethyl 2-[(3-methyl-2,5-dioxo(3-pyrrolinyl))amino]-4-(trifluoromethyl)pyrimidine- 5-carboxylate: An inhibitor of AP-1 and NF-κB mediated gene expression

Several analogues of ethyl 2-[(3-methyl-2,5-dioxo(3-pyrrolinyl))amino]-4-(trifluoromethyl)pyrimidine- 5-carboxylate (1) were synthesized and tested as inhibitors of AP-1 and NF-κB mediated transcriptional activation in Jurkat T cells. From our SAR work, ethyl 2-[(3-methyl-2,5-dioxo(3-pyrrolinyl))-N-methylamino]-4-(trifluoromethyl)- pyrimidine-5-carboxylate was identified as a novel and potent inhibitor.

Inhibitors of NF-kappaB and AP-1 gene expression: SAR studies on the pyrimidine portion of 2-chloro-4-trifluoromethylpyrimidine-5-[N-(3', 5'-bis(trifluoromethyl)phenyl)carboxamide].

We investigated the structure-activity relationship studies of N-[3, 5-bis(trifluoromethyl)phenyl][2-chloro-4-(trifluoromethyl)pyrimidin-5 -yl]carboxamide (1), an inhibitor of transcription mediated by both NF-kappaB and AP-1 transcription factors, with the goal of improving its potential oral bioavailability. Compounds were examined for cell-based activity, were fit to Lipinski's rule of 5, and were examined for potential gastrointestinal permeability using the intestinal epithelial cell line, Caco-2. Selected groups were substituted at the 2-, 4-, and 5-positions of the pyrimidine ring using solution-phase combinatorial methodology. The introduction of a fluorine in the place of 2-chlorine of 1 resulted in a compound with comparable activity. However, other substitutions at the 2-position resulted in a loss of activity. The trifluoromethyl group at the 4-position could be replaced with a methyl, ethyl, chlorine, or phenyl without a substantial loss of activity. The carboxamide group at the 5-position is critical for activity. If it was moved to the 6-position, the activity was lost. The 2-methyl analogue of 1 (81) showed comparable in vitro activity and improved Caco-2 permeability compared to 1.
