Reaction Conditions

Reaction Steps

500 mg (2.85 mmol) of (2-hydroxy-propyl)-carbamic acid t-butyl ester was dissolved in 10 mL of dichloroethane, then 0.44 mL (4.24 mmol) of ethyl diazoacetate was added thereto. 38 mg (0.085 mmol) of rhodium acetate was added to the reaction and then heated to 80° C. for 2 hours. The solvent was distilled off under reduced pressure, and the residue was purified by column chromatography to give 381 mg (1.45 mmol) of the title compound in a yield of 50%.
