Lightbrown to brown crystalline powder | [Synthesis]
The preparation process of pyrimidine includes the first α -alkylation reaction between diethyl malonate and allyl bromide, and the subsequent cyclization reaction with amidine to obtain a six-membered ring of bislactam. The chlorination of carbonyl with phosphorus oxychloride to obtain dichloro pyrimidine ring, followed by the oxidation of the terminal double bond with potassium osmate hydrate and sodium periodate to obtain the aldehyde group. The final reaction with ammonia water to produce SNAr/cyclization reaction, a five-step reaction, total yield of 45.8% to obtain 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine.
