Reference of 41253-21-8, The chemical industry reduces the impact on the environment during synthesis 41253-21-8, name is Sodium 1,2,4-triazol-1-ide, I believe this compound will play a more active role in future production and life.
(3) Synthesis of intermediate 5-(4-chlorobenzyl)-2-methoxymethoxymethyl-2-methyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol (Compound (VII), R1 =CH3, Ym =4-Cl, G=CH2OCH3, A=N)1H-1,2,4-Triazole sodium salt (1.196g, 13.1 mmol) was dissolved in NMP (7 ml), and heated to an internal temperature of 115 degrees C. To this, 5-(4-chlorobenzyl)-2-methoxymethoxymethyl-2-methylcyclopentanone (Compound (IX), R1 =CH3, Ym =4-Cl, G=CH2OCH3) (2.60 g, 8.76 mmol) was added, and washed thoroughly with NMP (1.8 ml). After the internal temperature became 115 degrees C again, sodium t-butoxide (505 mg, 5.26 mmol) and trimethylsulfoxonium bromide (2.2379 g, 1.476 mmol) were added in portions over about 3 hours. After completion of the addition, stirring was conducted at the same temperature for 75 minutes. The reaction solution was cooled to 35 degrees C, and then, to the reaction solution, water was added and extraction with ethyl acetate was conducted. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was distilled away and the residue was subjected to silica gel column chromatography (eluent; hexane:ethyl acetate =3:1 to 0:1) for purification to obtain the desired substance. Product: 2.36 gYield: 71 %Description: Colorless viscous oil
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, Sodium 1,2,4-triazol-1-ide, other downstream synthetic routes, hurry up and to see.
