Procedure

To a solution of (S)-1,4-dioxaspiro[4.5]decane-2-carbaldehyde oxime (9.08 g, 49 mmol) in DMF (50 mL) was added 1-chloropyrrolidine-2,5-dione (7.20 g, 53.9 mmol) and the reaction stirred overnight at ambient temperature. The reaction was poured into water (500 mL) extracted with ether. The organics were washed with brine and dried over magnesium sulfate. The material was concentrated in vacuo to yield (R)-N-hydroxy-1,4-dioxaspiro[4.5]decane-2-carbimidoyl chloride (10.4 g, 47 mmol, 96.6%).
