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 7170-01-6 as follows. 7170-01-6
41. 5-(3-Methyl-1H-1,2,4-triazole-1-yl)-1,6-naphthyridin-2(1H)-one–A stirred mixture containing 13.5 g of 5-bromo-1,6-naphthyridin-2(1H)-one, 20 g of 3-methyl-1H-1,2,4-triazole and 75 ml of N-methylpyrrolidinone was heated in an oil bath at 170-180 C. for 18 hours and then cooled to room temperature whereupon a tan solid crystallized out. The mixture was diluted by adding 125 ml of water and the separated solid was collected, washed with water, air-dried and combined with another 1.2 g sample of the same material obtained in another run starting with 2.25 g of 5-bromo-1,6-naphthyridin-2(1H)-one. The combined solids were recrystallized from dimethylformamide and dried in an oven at 95-100 C. for three days to yield 6.1 g of 5-(3-methyl-1H-1,2,4-triazole-1-yl)-1,6-naphthyridin-2(1H)-one, m.p. >300 C.
According to the analysis of related databases, 7170-01-6, the application of this compound in the production field has become more and more popular.
