Synthetic Route of 3680-69-1, Adding some certain compound to certain chemical reactions, such as: 3680-69-1, name is 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine,molecular formula is C6H4ClN3, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3680-69-1.
3H, m), 2.4 (3H, s), 1.31 (3H, J=6.8 Hz, d); MS (ES+) [M+H]+=455.6.15. Example 15(S)-N-(3-bromophenyl)-4-(5-chloro-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-N’-cyano-2-methylpiperazine-1-carboximidamide A. Preparation of 4,5-dichloro-7H-pyrrolo[2,3-d]pyrimidine: 4-Chloro-pyrrolo[2,3-d]pyrimidine (0.5 g, 3.26 mmol) was suspended in anhydrous CH2Cl2 (25 ml), and N-chlorosuccinimide (0.87 g, 6.52 mmol) was added. The reaction mixture was refluxed for 3 days, then cooled to room temperature. The white solid was collected by filtration to give 5-dichloro-7H-pyrrolo[2,3-d]pyrimidine (0.54 g, 2.9 mmol, 88%).1H NMR (CD3OD): delta 8.57 (1H, s), 7.60 (1H, s); MS (ES+) [M+H]+=188.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 3680-69-1, 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine, other downstream synthetic routes, hurry up and to see.
