Hydrogen Peroxide → HCID 66720698, compound

Participants

Reaction Steps

To 5-amino-2-(methylsulfanyl)-4-phenylthiazole (305 mg, 1.37 mmol) in acetic acid (3.0 ml) was added aqueous hydrogen peroxide (660 μl, 30% wt, 6.9 mmol) dropwise at ambient temperature. After 4 hr the mixture was partitioned between dichloromethane (60 ml) and water (60 ml). The organic phase was separated, washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. Flash chromatography on silica gel (ethyl acetate/hexanes) yielded pure 5-amino-2-(methylsulfinyl)-4-phenylthiazole (285 mg, 87%).
