39806-90-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 39806-90-1 as follows.
General procedure: 4-Iodo-1-methyl-1H-pyrazole 1 (101 mg, 0.5 mmol) and phenylboronic 2 (59 mg, 0.5 mmol) were dissolved in DME (3 mL) and H2O (1.2 mL) in a microwave vial under a nitrogen atmosphere. Pd(PPh3)4 (2 mmol%, 11.6 mg) and Cs2CO3 (407.3 mg, 1.25 mmol) were added, and the reaction mixture was irradiated in a microwave apparatus at 90 C for 5-12 min. After the reaction mixture was cooled to ambient temperature, the product was concentrated, and the crude mixture was purified by silica gel column chromatography using petroleum ether/acetone as eluent to give the title compound.
