Combine 2-methoxy benzamide (10.0 g, 66.2-mmol) with phosphorus pentasulfide (10.1 g, 22.7 mmol) and THF (200 mmol) in a sealed vessel and stir for 30 minutes at room temperature. Sonicate the mixture for 1 hour and then allow the mixture to stand at room temperature. Decant the THF solution from the solids and concentrate. Chromatograph the resulting residue over silica gel (MeOH/CH2Cl2) to give 2-methoxy-thiobenzamide (7.05 g, 64%).
