Procedure

Benzoyl chloride (5.14 mL, 44.28 mL) was added dropwise to a mixture of 4-aminophenol disulfide (5.0 g, 20.13 mmol) and TEA (7.01 mL, 50.3 mmol) in 60 mL DCM at 0° C. The reaction was allowed to stir overnight. The resulting precipitate was collected by filtration. The solid was washed with MeOH and water and then dried. The solid was combined with 200 mL of concentrated HOAc, and 5.0 equiv of zinc powder was added. The reaction was monitored by LCMS. When the reaction was complete, the acetic acid solution was concentrated to approximately 20 mL in volume. The crude mixture was then extracted with water and EtOAc. The organic layer was dried with MgSO4 then concentrated. MS: 228 [M+H]+; 1H NMR (DMSO-d6): 10.23 (s, 1H), 7.94 (d, 2H), 7.81 (d, 2H), 7.56 (m, 3H), 7.28 (d, 2H), 5.31 (s, 1H).
