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 941685-26-3, name is 4-Chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows. HPLC of Formula: C12H18ClN3OSi

A 1000 mL round bottom flask was charged with 4-chloro-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine (10.00 g, 35.23 mmol), 1-butanol (25.0 mL), 1-(1-ethoxyethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (15.66 g, 52.85 mmol), water (25.0 mL) and potassium carbonate (12.17 g, 88.08 mmol). This solution was degased 4 times, filling with nitrogen each time. To the solution was added tetrakis(triphenylphosphine)palladium(0) (4.071 g, 3.523 mmol). The solution was degased 4 times, filling with nitrogen each time. The mixture was stirred overnight at 100 C. After being cooled to room temperature, the mixture was filtered through a bed of celite and the celite was rinsed with ethyl acetate (42 mL). The filtrate was combined, and the organic layer was separated. The aqueous layer was extracted with ethyl acetate. The organic extracts were combined and concentrated under vacuum with a bath temperature of 30-70 C. to give the final compound 4-(1H-pyrazol-4-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine. Yield: 78%. LC-MS: 316.2 (M+H)+.

With the rapid development of chemical substances, we look forward to future research findings about 941685-26-3.
