In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4774-34-9, name is 4-Hydroxypyrimidine-5-carbonitrile, the common compound, a new synthetic route is introduced below. category: pyrimidines
EXAMPLE 76 4-(1,2,4,5-Tetrahydro-benzo[d]azepin-3-yl)-pyrimidine-5-carbonitrile In analogy to the procedure described in example 4 the 4-chloro-pyrimidine-5-carbonitrile (prepared from 4-hydroxy-5-pyrimidine-carbonitrile and phosphorus oxychloride, phosphorus pentachloride and N-ethyl-N,N-diisopropylamine in acetonitril at reflux) was treated with 2,3,4,5-tetrahydro-1H-benzo[d]azepine hydrochloride [J. Heterocycl. Chem. (1971), 8(5), 779-83] in N,N-dimethylformamide in the presence of N-ethyl-N,N-diisopropylamine at room temperature to yield the 4-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-pyrimidine-5-carbonitrile as off white solid; MS: [M+H]+=251; m.p. 148-150 C.
The synthetic route of 4774-34-9 has been constantly updated, and we look forward to future research findings.
