Participants

Reaction Steps

To a solution of methyl 5-(piperazin-1-yl)-4H-1,2,4-triazole-3-carboxylate (1.0 g, 4.44 mmols) in DCM (10 mL) was added (BOC)2O (0.970 g, 4.44 mmol), DMAP (0.050 g, 0.41 mmol), DIEA (3.9 mL, 22.4 mmol). The reaction was stirred at RT overnight. Reaction concentrated and ISCO purification (0-5% MeOH in DCM) to obtain tert-butyl 4-(5-(methoxycarbonyl)-4H-1,2,4-triazol-3-yl)piperazine-1-carboxylate (0.580 g).
