Adding a certain compound to certain chemical reactions, such as: 4314-22-1, name is 2-(1H-1,2,3-Triazol-1-yl)acetic acid, belongs to triazoles compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4314-22-1, Application In Synthesis of 2-(1H-1,2,3-Triazol-1-yl)acetic acid
Oxalyl chloride (0.95 mL, 11 mmol) was added dropwise to a suspension of 2- (1- 1, 2,3-triazolyl)) acetic acid (Step B, 1.27 g, 10 mmol) in 10 mL CH2C12 containing 0.05 mL DMF. Vigorous effervescence was observed. This mixture was stirred at room temperature for 4 h and cooled to-78C. A solution of N. O- dimethylhydroxylamine hydrochloride (1.2 g, 13 mmol) and diisopropylethyl amine (6.0 mL, 35 mmol) in 10 mL CH2C12 was added slowly over 3 min. The mixture was then allowed to warm to room temperature and stirred overnight. The reaction mixture was then diluted with ether until no additional precipitate appeared. The solid was filtered and washed with ether. The filtrate was concentrated and the residue was purified on silica gel using EtOAc as solvent to provide the title compound as amorphous solid. 1H NMR (400 MHz, CDC13) : 8 3.252 (s, 3H0, 3.812 (s, 3H), 5.379 (s, 2H), 7.753 & 7.761 (s’s, 2H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(1H-1,2,3-Triazol-1-yl)acetic acid, other downstream synthetic routes, hurry up and to see.
