Synthetic Route of 7170-01-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of compound GX (i g, 2.91 mmol) in DMF (10 mL) under argon atmosphere were added potassium carbonate (602 nig, 4.36 mmol) and 3-methyl-lH-l ,2,4- triazoie (483 mg, 5.82 mmo) at RT. The reactioii mixture was stirred at 80 C for 16 Ii. The reaction mixture was diluted with water (50 mL) and extracted with EfOAc (2 x 50 mL). The combined organic layers were dried over anhydrous NaiSC^ and concentrated under reduced pressure. The crude material was purified by silica gel column chromatography (eluent: 50% EtOAc/Hexane) which was further purified by preparative HPLC to afford compound JL (550 nig, 1.29 mmol, 44%) & compound JM (550 nig. 1.2 mniol, 44%) as an off-white solids. JL data: 5H NMR (500 MHz, DMSO-(): 5 8.71 (s, 1H), 8.15 (dd, J= 8.7, 2.3 Hz, 1H), 8.01 (s, 1H), 7.37 (d, J = 8.1 Hz, 1H), 7.31-7.24 (ni. IH), 7.24-7.18 (in, 1H), 7.17-7.14 (m, 1H), 7.09- 7.05 (m, 1H), 6.79 (s, IH), 5.15 (d, J = 14.5 Hz, 1H), 4.75 (d, J= 15.1 Hz, IH), 2.04 (s, 3H); JM data: 1H NMR (500 MHz, DMSO-?): S 8.71 (s, 1H), 8.17 (dd, J= 8.1, 2.3 Hz, 1H)5 7.56 (s, 1H), 7.44 (d J= 8.1 Hz, lH), 7.33-7.27 (ni, 1H), 7.26-7.22 (m, IH), 7.19-7.16 (m, 1H), 7.10-7.06 (m, 1H), 6.66 (s, 1H). 4.98 (d, /= 14.49 Hz, IH), 4.86 (d. /= 13.91 Hz, IH), 2.22 (s, 3H).
The synthetic route of 3-Methyl-1H-1,2,4-triazole has been constantly updated, and we look forward to future research findings.
