Reference of 13423-60-4, A common heterocyclic compound, 13423-60-4, name is 1-Phenyl-1H-1,2,4-triazole, molecular formula is C8H7N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
EXAMPLE 113 1-phenyl-4-(hepr-1-yl)triazolium bromide 0.150 g (0.002 mol) 1-phenyltriazole 1 (actually, 0.3 g, there were still 2 eq. DMF contained in the educt) and 0.97 ml (1.110 g, 0.006 mol) 1-bromoheptane 2 are combined in a pressure tube. The reaction mixture was stirred 12 h at 110 C. The reaction mixture is cooled down and the same volume petroleum ether is added. The precipitated solid is filtered off, washed with petroleum ether, and dried in HV. M 324.26 C15H22N3Br Yield: 0.225 g (69%) 1H-NMR DM-170 (300 MHz/DMSO): delta (ppm)=0.87 (t, 3H, 13-H); 1.30 (m, 8H, 9/10/11/12H); 1.95 (qui, 21-1,8-H); 4.34 (t, 2H, 7-H); 7.68 (m, 3H, 5/5’/6H); 7.95 (d, 2H, 4/4′-H); 9.55 (s, 1H, 1-H); 11.10 (s, 1H, 2-H) 13C-NMR DM-170 (300 MHz/DMSO):
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
