The chemical industry reduces the impact on the environment during synthesis 4314-22-1, name is 2-(1H-1,2,3-Triazol-1-yl)acetic acid, I believe this compound will play a more active role in future production and life. 4314-22-1
Step C N-Methoxy-N-methyl-2-(1-(1, 2, 3-triazolyl)) acetamide 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.
