Synthetic Route of 63200-54-4 , The common heterocyclic compound, 63200-54-4, name is 2,4-Dichloro-5H-pyrrolo[3,2-d]pyrimidine, molecular formula is C6H3Cl2N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
General procedure: A mixture of 2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine 18a (51.3 g) and 1.36 L of 1 N NaOH was stirred at 80 C overnight. The solution was subsequently chilled and adjusted to pH 6 with AcOH. The resulting precipitate was collected, washed with water and dried to afford 19a as solid (37.3 g, yield: 80.7%).
The synthetic route of 63200-54-4 has been constantly updated, and we look forward to future research findings.
