Synthetic Route of 4922-51-4, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 4922-51-4, name is 4-(4H-1,2,4-Triazol-3-yl)aniline, molecular formula is C8H8N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
EXAMPLE 6 Preparation of (3Z)-3-{[4-(1H-1,2,4-triazol-3-yl)anilino]methylene}-1,3-dihydro-2H-indol-2-one Prepared in an analogous manner to Example 1 using one equivalent of 4-(1H-1,2,4-triazol-3-yl)aniline in place of 5-aminobenzimidazolone. 1H NMR (400 MHz, d6-DMSO) delta14.32 (s, 1H, exchangeable); 14.05 (s, 1H, exchangeable); 10.82 (m, 1H); 10.54 (m, 1H); 8.64 (m, 1H); 8.60 (s, 1H, exchangeable); 8.00 (m, 2H); 7.63 (m, 1H); 7.47 (m, 1H); 7.03 (m, 1H); 6.94 (m, 1H); 6.85 (m, 1H). APCI MS (-ve) 302.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 4-(4H-1,2,4-Triazol-3-yl)aniline.
