Conditions

Temperature: 150 °C

Procedure

A mixture of methyl 3-(4-{6-[N′-(4-methoxybenzoyl)-hydrazinocarbonyl]-1H-indol-2-yl}-3,5-dimethyl-phenyl)-propionate (220 mg, 440 μmol) and Burgess reagent (210 mg, 880 μmol) in THF (10 mL) was heated in a microwave apparatus at 150° C. for 30 min. The solvent was removed under reduced pressure, and the residue chromatographed using a 30-70% gradient of heptane/ethyl acetate to afford the title compound.
