Synthetic Route of 955368-90-8, 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 955368-90-8, name is 2-Allyl-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-3(2H)-one. This compound has unique chemical properties. The synthetic route is as follows.
I1 (1.0 g, 4.5 mmol) was added into 1,4- dioxane (10 mL), and 2-bromo-6-methoxylpyridine (1.02 g, 5.4 mmol, 664 muL), potassium carbonate (622 mg, 4.5 mmol), cuprous iodide (857 mg, 4.5 mmol) and N,N’-dimethylethylenediamine (397 mg, 4.5 mmol, 490 muL) were added while stirring, heated to 95C under nitrogen atmosphere, then reacted for 12 h. 100 mL ammonia was added into the reacted mixture, then extracted by 100 mL EA, the organic phase was washed by 100 mL brine, dried over anhydrous sodium sulfate, filtered and concentrated, the crude product was crystalized by EtOAc, then purified by silica gel chromatography (PE/EA = 10/1 to 2/1), to give the compound 47-1. 1H NMR (400MHz, CDCl3) delta = 8.92 (s, 1H), 7.89 (t, J=8.0 Hz, 1H), 7.43 (d, J=7.2 Hz, 1H), 6.82 (d, J=8.0 Hz, 1H), 5.83 – 5.69 (m, 1H), 5.07 (d, J=10.4 Hz, 1H), 4.96 (br d, J=17.2 Hz, 1H), 4.84 (d, J=6.0 Hz, 2H), 3.93 (s, 3H), 2.56 (s, 3H)
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 955368-90-8, 2-Allyl-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-3(2H)-one.
