With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.171879-99-5,4-Chloro-6-methyl-7-azaindole,as a common compound, the synthetic route is as follows.
A mixture of 4-chloro-6-methyl-1 H-pyrrolo[2,3-b]pyridine (47mg, 0.291 mmol), 3-(4,4,5,5- tetramethyl-1 ,3,2-dioxaborolan-2-yl)pyrazolo[1 ,5-b]pyridazine (107mg, 0.436mmol), X Phos Pd G3 (19.6mg, 0.023mmol) and potassium phosphate (124mg, 0.582mmol) in degassed ethanol (3.0ml_) and water (1.5ml_) was heated at 140C for 30 mins in the microwave. After cooling it was partitioned between ethyl acetate and water and the organic layer was separated, washed with brine, dried (Na2S04) and concentrated in vacuo. The crude product was purified by MDAP (Basic) to afford the title compound as a glass (27mg, 37%) LCMS (Method 1): Rt 2.12 min, m/z 249.8 [MH+]. 1 H NMR (400 MHz, d6-DMSO): 2.59 (3H, s), 6.56 (1 H, d, J=3.5 Hz), 7.19 (1 H, s), 7.34 (1 H, dd, J=4.4, 9.1 Hz), 7.43 (1 H, d, J=3.5 Hz), 8.48 (1 H, dd, J=1.8, 9.2 Hz), 8.56- 8.58 (2H, m), 11.59 (1 H, s), 171879-99-5
The synthetic route of 171879-99-5 has been constantly updated, and we look forward to future research findings.
