Related Products of 327-74-2,Some common heterocyclic compound, 327-74-2, name is 2-Amino-5-cyanobenzotrifluoride, molecular formula is C8H5F3N2, 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.
4-Amino-3-trifluoromethylbenzonitrile (100mg, 0.54mmol) and lCl(1.1eq, 0.58mmol, 96.00mg) were added to methylene chloride. The mixture was stirred for 12hrs. The reaction mixture was purified accoding to step 2 of Example 8 to give the title compound (30.5mg, 18.10%). mp: 86~88 C; IR(KBr pellet, cm-1): 3371, 3080, 2924, 2226, 1125, 701; 1H NMR(400MHz, CDCl3): delta 8.02 (d, 1 H, J=1.6Hz), 7.35 (dd, 1 H, J=133.2, 1.6Hz), 7.65 (dd, 1H, J=10.0, 1.6Hz), 5.20 (d, 2H, J=22.0Hz).
The synthetic route of 327-74-2 has been constantly updated, and we look forward to future research findings.
