The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
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.
