Reaction Steps
Methyl 1-methyl-1H-1,2,4-triazole-3-carboxylate (280 mg) and methanol (1 ml) were added to potassium hydroxide (145 mg) in water (1 ml). The reaction was stirred for 3 h at RT. The solvent was evaporated and the residue was loaded onto an aminopropyl SPE cartridge (5 g) in DMF. The cartridge was washed with 10% methanol in DCM (3×15 ml), followed by 30% acetic acid in methanol. The appropriate fractions were combined, the solvent was evaporated and the residue dried at 50° C. under vacuum to give title compound (180 mg).
