Hydrogen Peroxide → HCID 88295758, compound

Participants

Reaction Steps

A mixture of N-acetyl-L-cysteine (0.652 g, 4 mmol) and N-isobutyryl-L-cysteine (0.764 g, 4 mmol) in 10 mL of MeOH was stirred while hydrogen peroxide (30%, 0.60 mL, 5 mmol) was added dropwise. The stirring was continued for 3 hours at room temperature, after which the solvent was removed on the rotary evaporator. Addition of 25 mL of acetone and repeated evaporation afforded 1.5 g of crude material as an oil which solidified on standing. The desired title compound was isolated from this mixture by preparative HPLC as described in Example 17.
