Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 39806-90-1, name is 4-Iodo-1-methyl-1H-pyrazole, A new synthetic method of this compound is introduced below., Safety of 4-Iodo-1-methyl-1H-pyrazole
To a solution of 3-iodo-l-methyl-lH-pyrazole (20 mg, 0.096 mmol) and intermediate C.5 (20 mg, 0.074 mmol) in anhydrous l,4-Dioxane (1 ml) was added (Irans)-N I .N2-dimethylcyclohexane- 1, 2-diamine (5 mg, 0.035 mmol), Cul (5 mg, 0.026 mmol) and K3PO4 (50 mg, 0.236 mmol). The resulting mixture was stirred at 90C for 16 hours. After filtering and concentrating the reaction solution, the residue was purified by prep-HPLC (basic) to afford example 6.1, 5-methyl-l-(l- methyl-lH-pyrazol-4-yl)-6-(l-(oxetan-3-yl)piperidin-4-yl)-lH-indazole. MS (ESI) m/z calc?d for C20H26N5O [M+H]+ 351, found 351. -NMR (500 MHz, CDC13) d 8.00 (s, 1H), 7.82 (s, 1H), 7.73 (s, 1H), 7.53 (s, 1H), 7.42 (s, 1H), 4.66-4.71 (m, 4H), 4.02 (s, 3H), 3.51-3.57 (m, 1H), 2.92 (m, 2H), 2.85 (m, 1H), 2.45 (s, 3H), 1.97-2.02 (m, 2H), 1.87 (m, 4H). LRRK2 IC50 1.1 nM.
The synthetic route of 39806-90-1 has been constantly updated, and we look forward to future research findings.
