Reaction Conditions

Temperature	150 °C

Reaction Steps

A suspension of compound 5 (400 mg, 0.99 mmol) and Lawesson's Reagent (402 mg, 0.99 mmol) in anhydrous 1,4-dioxane (15 mL) was stirred at 150° C. for 30 min in a CEM microwave reactor. The mixture was concentrated in vacuo, and the residue was purified by prep-TLC to give compound 6 (140 mg, 34%) as a white solid.
