Related Products of 941685-26-3 ,Some common heterocyclic compound, 941685-26-3, molecular formula is C12H18ClN3OSi, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
4-chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (2.50 g, 8.80 mmol), compound (39c) (4.60 g) and potassium carbonate (3.10 g, 22.08 mmol) were placed in a 100 mL flask, dioxane (50 mL) and water (6 mL) were added, the reaction was stirred until homogeneous, Pd(dppf)Cl2 (370 mg) was then added, nitrogen replacement was performed for 2-3 times, and the flask was placed in an oil bath at 100C. The reaction was allowed to proceed overnight. After LC-MS indicated the substrate disappeared, insolubles were filtered off through Celite, the solvent was rotary evaporated off, and the residue was dissolved in EA, washed with water to obtain the organic phase, which was dried over anhydrous sodium sulfate, and purified by preparative flash chromatography (PE:EA=3:2), to afford compound (39d) (1.67 g, yellow solid), yield: 56%. MS m/z: 243 [M+1]+.
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. 941685-26-3, 4-Chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine, other downstream synthetic routes, hurry up and to see.
