Methyl iodide → Methyl 2-(methylsulfanyl)-5-nitrobenzoate

Participants

Reaction Steps

Combine 2-methylthio-5-nitrobenzoic acid, (3.2 g, 15 mmol), N,N-diisopropylethylamine (17.0 mL, 100 mmol), and methyl iodide (12.45 mL, 200 mmol) in acetonitrile (50 mL). After 18 hours, dilute the reaction mixture with ethyl acetate, extract with brine, dry the organic layer over MgSO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 20% ethyl acetate/hexane to give methyl 2-methylthio-5-nitrobenzoate. Rf==0.58 (silica gel, 30% ethyl acetate/hexane).
