Electric Literature of 876343-10-1, 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 876343-10-1, name is 4-Chloro-6-iodo-7H-pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 4-chloro-6-iodo-7H-pyrrolo[2,3-d]pyrimidine (10 g, 35.8 mmol) in DMF (120 ml) at 0C was added portionwise NaH (60%) in mineral oil (1 .7 g, 42.5 mmol) under argon. The resulting suspension was stirred at 0C for 30 min., 2-(trimethylsilyl)ethoxymethyl chloride (7.5 ml, 42.3 mmol) was added and the RM was allowed to warm to RT for over 1 h. The RM was then poured carefully into ice water and extracted with Et20. The combined organic phases were washed with brine and evaporated. The residue was diluted with ACN and the resulting mixture was filtered to give of the title compound as a solid (8.052 g). The filtrate was concentrated, triturated in cold MeOH and filtered to give a second crop of the title compound as a solid (3.120 g).Method A: Rt = 1 .48 min; [M+H]+= 410.1 .
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 876343-10-1, 4-Chloro-6-iodo-7H-pyrrolo[2,3-d]pyrimidine.
