Reaction Conditions

Reaction Steps

To a solution of compound 2 (68 mg, 0.149 mmol) in dry toluene (2 mL) was added Lawesson's reagent (91 mg, 0.224 mmol) under N2. The reaction mixture was heated in a CEM microwave reactor at 130° C. for 1 h. The solvent was removed under reduced pressure, and the residue was purified by preparative TLC (petroleum ether:EtOAc=3:1) to give compound 3 (46 mg, 66%) as a white solid.
