Quality Control of Sodium 1,2,4-triazol-1-ide

1.4: tert-butyl 4-cyclohexyl-4-(1H-1,2,4-triazol-1-ylmethyl)piperidine-1-carboxylate 7.83 g of tert-butyl 4-cyclohexyl-4-{[(methylsulphonyl)oxy]methyl}-piperidine-1-carboxylate and 5.68 g of sodium 1,2,4-triazole are introduced into a 100 ml round-bottomed flask under N2. 42 ml of dimethylformamide are added. After reaction in a microwave at 150 C. for 1 h 30 min and with a power of 150 W, the product is hydrolyzed and extracted with ethyl acetate until the aqueous phase is completely depleted. The organic phase is washed with H2O and concentrated to dryness. After crystallization from hexane, 4.42 g of tert-butyl 4-cyclohexyl-4-(1H-1,2,4-triazol-1-ylmethyl)piperidine-1-carboxylate are obtained. 1.5: 4-cyclohexyl-4-(1H-1,2,4-triazol-1-yl-methyl)piperidine 11.2 g of tert-butyl 4-cyclohexyl-4-(1H-1,2,4-triazol-1-ylmethyl)-piperidine-1-carboxylate are placed in 80 ml of 4N hydrochloric acid in dioxane. The reaction medium is stirred for 16 h at ambient temperature. After evaporation to dryness, the precipitate obtained is filter-dried and rinsed with diethyl ether. The hydrochloride thus obtained is dried over P2O5 under reduced pressure. 9.65 g of 4-cyclo-hexyl-4-(1H-1,2,4-triazol-1-ylmethyl)piperidine are obtained.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 41253-21-8
