Potassium Carbonate → HCID 22938523, compound

Participants

Reaction Steps

methyl 1,2,3-triazole-4-carboxylate (17.6 g) was dissolved in DMF (210 ml), potassium carbonate (11.5 g) and iodopropane (14.9 ml) were added to the mixture, and the mixture was stirred for 16 hours at room temperature. After filtration, the solvent was removed under reduced pressure, and water was added to the obtained residue, and the mixture was extracted with methylene chloride. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give methyl 2-propyl-1,2,3-triazole-4-carboxylate (10.3 g), methyl 1-propyl-1,2,3-triazole-5-carbonate (3.2 g) and methyl 1-propyl-1,2,3-triazole-4-carboxylate (2.6 g).
