Application of 3680-69-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 3680-69-1, name is 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
Example 1 Preparation of 5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine The solution of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (6.08 g, 39.07 mmol) in CH2Cl2 (100 mL) was heated to 60 C. for for 30 min. A solution of NBS (5.40 g, 39.07 mmol) in CH2Cl2 (100 mL) was added slowly in portions to this mixture. The mixture was refluxed for an additional 50 min and allow to cool to rt. Filter off the off white solid and washed with water, dried in vacuum oven to give 7.7 g of 5-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine. MS (ESI) 234.5 (M+H)+.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 3680-69-1, 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine.
