Procedure
To a 100 mL flask was added N-cyclohexylmethyl-(2-oxoethyl)-carbamic acid benzyl ester bisulfate adduct (3.94 g, 1 mmol) and MeTHF (35 mL), followed by water (25 mL). The resulting slurry was stirred at room temperature for 5 min and 1M NaOH (8 mL) was added. The reaction mixture was stirred at room temperature for 45 min. The layers were separated and the volume of the organic layer was reduced to ˜8 mL to provide the crude title intermediate.
