Lawesson's reagent → Ethyl 6'-bromo-1'-(1,1-dimethylethylsulfinamido)-4-methoxy-1',3'-dihydrospiro[cyclohexane-1,2'-indene]-1'-carboxylate

Participants

Reaction Steps

An 8 mL vial was charged with compound 5 (20 mg, 0.0446 mmol), Lawesson's reagent (19.9 mg, 0.0491 mmol). Toluene (3 mL) was added, and the vial was sealed and placed into CEM microwave reactor and irradiated at 130° C. for 1 h. After cooling down, the solvent was removed by evaporation in vacuo and the resulting residue was purified by preparative TLC (hexane: EtOAc=2:1) to give compound 6 (10 mg, 47%) as a white solid.
