Reaction Steps

Sodium hydride (60% dispersion in mineral oil, 281 mg, 7.0 mmol) was added to a solution of phenylmethyl 3-oxo-1-piperazinecarboxylate (1.5 g, 6.4 mmol) in dry dimethyl formamide (5 mL) and the mixture was stirred at room temperature for 30 minutes. 5-(Chloromethyl)-1-methyl-1H-1,2,4-triazole (WO0023449, 920 mg, 7.0 mmol) was added and the mixture was stirred at room temperature for 16 hours. The mixture was poured into water (150 mL) and extracted with diethyl ether (2×100 mL). The combined organic fractions were dried (MgSO4) and the solvent was evaporated under reduced pressure to give the title compound as a pale oil (2 g, 94%). m/z (ES+) 330 (M+1).
