Adding a certain compound to certain chemical reactions, such as: 252742-72-6, name is 3-(Chloromethyl)-1H-1,2,4-triazol-5(4H)-one, 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 252742-72-6, Safety of 3-(Chloromethyl)-1H-1,2,4-triazol-5(4H)-one
A solution of 33A (0.105 g 0.77 mmol) in DMF (5 mL) was treated with KN(SiMe3)2 (0.5 M/toluene, 1.8 mL, 0.93 mmol), stirred at 0° C. for 20 min, and then treated with 33B (0.155 g 1.16 mmol, Tetrahedron Letters 2000, 41, 8661). The reaction was warmed to 20° C., stirred 2 h, and concentrated. The residue was then treated with 0.5 N NaOH (10 mL) and washed with CH2Cl2 (3.x.). The aqueous layer was concentrated and subjected to chromatography (20-80percent EtOAc/hexanes) to provide 33 as a white solid (0.065 g, 36percent). LMCS m/z 234 (MH+).
