Sodium Hydroxide → HCID 19779518, compound

Participants

Reaction Steps

A solution of m-chloroperoxybenzoic acid (80% 16.6 g, 86.3 mmol) in methylene chloride (100 mL) was added dropwise to a solution of 1-[(3-chloropropyl)thio]-4-nitrobenzene (20.0 g, 86.3 mmol) in methylene chloride (20 mL) maintained at -78° C. (dry ice/acetone bath). After 2 h the reaction was allowed to warm to ambient temperature (~1 h) and 200 mL of 10% aqueous sodium hydroxide was added. The layers were allowed to separate and the aqueous layer was extracted (100 mL) with methylene chloride. The combined organic extracts were washed (water, 100 mL), dried (MgSO4) and concentrated in vacuo. A 1.0 g sample of the residue (21.2 g) was chromatographed (Chromatatron, SiO2 4000 μ, 99/1 methylene chloride:methanol) to give 0.89 g (88%) of white solid, mp 72.5°-74.5° C.
