Synthetic Route of 1421372-94-2, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1421372-94-2, name is N-(4-Fluoro-2-methoxy-5-nitrophenyl)-4-(1-methyl-1H-indol-3-yl)pyrimidin-2-amine, molecular formula is C20H16FN5O3, molecular weight is 393.3712, as common compound, the synthetic route is as follows.
3. Synthesis of intermediate 054-5 The intermediate 054-4 (400 mg, 1.02 mmol) as a raw material was dissolved in 5 mL of NMP in 100 mL three-necked flask at room temperature under a nitrogen atmosphere, followed by sequentially adding the intermediate 006-5 (400 mg, 2.37 mmol) and K2CO3 (907 mg, 6.56 mmol) into the reaction system. The reaction system was heated to 105C and carried out for 2 hours. After completion of the reaction, the reaction was cooled to room temperature, quenched by adding 30 mL of water. The reaction mixture was extracted with 30 mL of ethyl acetate three times. The organic phases were combined, washed with 30 mL of saturated brine three times, dried over anhydrous sodium sulfate and concentrated to dryness. The residue was purified by silica gel column chromatography (eluent: DCM / MeOH = 15: 1) to give 100 mg of the intermediate 054-5 (19%) as a white solid. LCMS: 519.6.
The chemical industry reduces the impact on the environment during synthesis 1421372-94-2, I believe this compound will play a more active role in future production and life.
