Step G: tert-Butyl 3-(6-(((tert-butyldimethylsilyl)oxy)methyl)-5-methylpyridin-2-yl)-3-(3-(difluoromethyl)-8-methyl-[1,2,4]triazolo[4,3-a]pyridin-7-yl)-2,2-dimethylpropanoate. InBr3 (501 mg, 1.41 mmol) was added to a solution of 7-((6-(((tert-butyldimethylsilyl)oxy)methyl)-5-methylpyridin-2-yl)chloromethyl)-3-(difluoromethyl)-8-methyl-[1,2,4]triazolo[4,3-a]pyridine (2.2 g, 4.7 mmol), ((1-(tert-butoxy)-2-methylprop-1-en-1-yl)oxy)trimethylsilane (10.2 g, 47.1 mmol), and dichloromethane (40 mL) under N2. The resultant mixture was stirred at room-temperature for 5 days, poured it into water (30 mL) and extracted with dichloromethane (3*). These extractions resulted in several fractions that were combined, washed with brine (30 mL), dried over anhydrous Na2SO4, filtered, and concentrated to dryness under reduced pressure. The residue was purified by flash chromatography (eluent:petroleum ether/ethyl acetate; 1:0 to 3:2, gradient) to afford the title compound (1.3 g, 48%), which was used in the next step without further purification.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13465-09-3,Indium(III) bromide,as a common compound, the synthetic route is as follows.

13465-09-3, Step C: Methyl 3-(6-(((tert-butyldimethylsilyl)oxy)methyl)-5-methylpyridin-2-yl)-3-(3-(difluoromethyl)-8-methyl-[1,2,4]triazolo[4,3-a]pyridin-7-yl)-2,2-dimethylpropanoate. InBr3 (228 mg, 0.643 mmol) was added to a 100 mL round-bottomed flask containing a solution of 7-((6-(((tert-butyldimethylsilyl)oxy)methyl)-5-methylpyridin-2-yl)chloromethyl)-3-(difluoromethyl)-8-methyl-[1,2,4]triazolo[4,3-a]pyridine (1.0 g, 2.1 mmol), ((1-methoxy-2-methylprop-1-en-1-yl)oxy)trimethylsilane (1.87 g, 10.7 mmol) and dichloromethane (30 mL) under N2. The resulting mixture was stirred at room temperature for 48 hours, then was poured into water (30 mL) and extracted with dichloromethane (30 mL*3). These extractions resulted in several organic solvent fractions which were combined, washed with brine (30 mL), dried over anhydrous Na2SO4, filtered, and concentrated to dryness under reduced pressure. The material was purified by FCC (petroleum ether/ethyl acetate=1:0 to 3:1) to give the title compound (460 mg, 37% yield). MS (ESI): mass calcd. for C27H38F2N4O3Si 532.3; m/z found, 533.3 [M+H]+.

As the paragraph descriping shows that 13465-09-3 is playing an increasingly important role.
