Reaction Steps

4-Bromo-3-methylbenzamide (D37, 1.0 g, 0.0047 mole) was dissolved in THF (50 ml), treated with Lawessons reagent (0.95 g, 0.0024 mole) and stirred under argon for 4 h. The solvent was removed in vacuo and the residue purified by flash chromatography on silica gel eluting with 10% EtOH/CHCl3 to afford the title compound as a yellow solid (0.87 g, 80%).
