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. 63200-54-4, name is 2,4-Dichloro-5H-pyrrolo[3,2-d]pyrimidine, the common compound, a new synthetic route is introduced below. Computed Properties of C6H3Cl2N3
General procedure: 2,4-dichloro-1H-pyrrolo[3,2-d]pyridine (5) was dissolved in a solution of 1:1 THF:DMF underN2. Sodium hydride (60% suspension in oil) was added directly, and the mixture was stirredat room temperature for 1 h. Appropriate halogenated reagent (methanesulfonyl chloride (6),2-nitrobenzenesulfonyl chloride (7), 2,4,6-Triisopropylbenzenesulfonyl chloride (8), benzyl bromide(9), 2,4-dichlorobenzyl bromide (10), 4-methoxybenzyl chloride (11), acetyl chloride (12), isobutyrylchloride (13), diphenylcarbamyl chloride (14), iodoethane (15)) was added and the mixture was stirredat r.t. for 18 h. The solvent was removed and residue dissolved in EtOAc and washed with waterand brine, then dried over MgSO4. Organics were loaded onto Celite and product purified usingsilica column chromatography eluting with 4:1 hexanes:EtOAc or 9:1 DCM:MeOH to obtain product,generally as a white to o-white solid.
The synthetic route of 63200-54-4 has been constantly updated, and we look forward to future research findings.
