1H-1,2,4-Triazole → HCID 59208302, compound

Participants

Reaction Steps

To a solution of 1,2,4-triazole (48.3 mg, 0.70 mmol) in DMF (2 ml) was added NaH (18.3 mg, 0.76 mmol). After 10 minutes stirring, 1,4-dibenzyl-2-(chloromethyl)piperazine (200 mg, 0.64 mmol) and KI (156 mg, 0.70 mmol) were added to the mixture. The mixture was stirred at 60° C. overnight. The mixture was diluted with EtOAc and washed with water and brine. The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The resulting residue was purified by column chromatography on NH-silica gel (Hex/AcOEt=¼) to give 1,4-dibenzyl-2-(1H-1,2,4-triazol-1-ylmethyl)piperazine (220.0 mg, 99.7%): HPLC-MS (ESI): Calcd for C21H25N5 [M+H]+ 348, found: 348.
