The downstream synthesis method of this compound is introduced below.
1. Synthesis of methyl 2-(thiazol-2-ylamino)isonicotinate A suspension of methyl 2-chloroisonicotinate (15.0 g, 87.42 mmol), 2-aminothiazole (10.50 g, 104.9 mmol), sodium carbonate (12.97 g, 122.4 mmol, 1.4 eq) and XANTPHOS (0.607 g, 1.049 mmol, 0.012 eq) in toluene (300 mL, bubbled with argon for 5 minutes) was bubbled again with argon for 5 additional minutes. Tris(dibenzylideneacetone)dipalladium (0) (0.320 g, 0.349 mmol, 0.004 eq) was then added to the suspension which was heated at 100° C. for 5 days. The mixture was cooled down to RT and filtered. The resulting solid was suspended in water and stirred for 1 hour. After filtration, the resulting solid was dried under vacuum overnight and afforded the title material (14.17, 69percent) as a solid. 1H NMR (400 MHz, DMSO-d6) delta (ppm): 3.90 (3H, s), 7.07 (1H, d, J=3.54), 7.32 (1H, dd, J=5.31, 1.26 Hz), 7.43 (1H, d, J=3.79 Hz), 7.61 (1H, s), 8.48 (1H, d, J=4.55 Hz), 11.56 (1H, s). LC/MS (M+H)+: 236. HPLC ret. time (Condition A): 1.182 min.
According to the analysis of related databases, 58481-11-1, the application of this compound in the production field has become more and more popular.
