Procedure

2-Acetamido-N-benzyl-2-bromoacetamide (prepared from 2-acetamido-N-benzyl-2-ethoxyacetamide (3.00 g, 12.0 mmol) and BBr3 (1M in CH2Cl2, 17.2 mL, 17.2 rental)) was dissolved in THF (250 mL), cooled (-10° C.), and then added dropwise (30 min) to a suspension of NH2OH (5-6 equiv) in THF (50 mL) at -10° C. The reaction mixture was stirred (30 min) at this temperature and then allowed to warm to room temperature (1 h). The insoluble materials were filtered and the filtrate was concentrated in vacuo. The residue was separated into two components by flash column chromatography on SiO2 gel (7.5% MeOH/CHCl3).
