Sodium hydride → 1-[(2-Phenyl-2H-1,2,3-triazol-4-yl)methyl]piperazine

Participants

Reaction Steps

To a stirred suspension of 0.28 g (0.71 mmol) of sodium hydride (60% mineral oil dispersion) in 5 mL anhydrous N,N-dimethylformamide at 0° C. was added 0.12 g (0.65 mmol) tert-butyl 1-piperazine-carboxylate. The resulting mixture was stirred under an atmosphere of nitrogen for 15 min and then allowed to warm to ambient temperature at which point 0.14 g (0.59 mmol) of 4-(bromomethyl)-2-phenyl-2H-1,2,3-triazole was added. After 4 h, quench the reaction with 25 mL cold water and extract the resulting solution with 25 mL ethyl acetate. The organic layer was washed with water (2×25 mL), dried over magnesium sulfate, filtered and evaporated in vacuo to afford the title compound which was purified by reverse-phase HPLC (TMC Pro-Pac C18; 10-100% 0.1% trifluoroacetic acid in acetonitrile/0.1% trifluoroacetic acid in water gradient). LC/MS: m/z (ES) 344.0 (MH)+.
