Synthetic Route of 7170-01-6, New Advances in Chemical Research in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 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.
Example 4; Preparation of Compound C’ from Compound B’ (Example 2); Compound B’ (60.00 g, 0.274 mol) (prepared as in Example 2) was added in portions to a melt of 3-methyl-1,2,4-triazole (113.8 g, 1.369 mol) under argon at 110-120 C. The mixture was heated to about 143 C. and the resulting solution was stirred at 142-44 C. for 17 h. After cooling to 120 C., 1-methyl-2-pyrrolidinone (NMP) (60 mL) was added quickly. The solution was further cooled to about 95 C. and water (300 mL) was added slowly (about 30 min.) keeping the temperature at 85 and 95 C. resulting in crystallization of the product. The slurry was cooled slowly to 0-5 C. and held for about 1 h. The cold slurry was filtered and the cake washed with cold H2O (2×75 mL) then dried in vacuo at 55 C. for 16 h affording 34.5 g Compound C’ as a crystalline, tan solid (54.9%), HPLC AP 98.2. If necessary, the product could be further purified by recrystallization from ethyl acetate. 1H NMR (400 MHz, CDCl3) delta 2.55 (s, 3H), 4.05 (s, 3H), 6.73 (dd, 1H, J=2.9, 2.6), 7.42 (dd, 1H, J=2.9, 2.8), 7.57 (s, 1H), 9.16 (s, 1H), 10.29 (bs, 1H). Anal. Calcd for C11H11N5O: C, 57.63; H, 4.84; N, 30.55. Found: C, 57.37; H, 4.74; N, 30.79.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 3-Methyl-1H-1,2,4-triazole, hurry up and to see.
