Reaktionsschritte

To a 100 mL flask was added N-cyclohexylmethyl-(2-oxoethyl)-carbamic acid benzyl ester bisulfite 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 1 M 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.
