HCID 21914741Methyl 3-(4-(methylthio)phenyl)propanoate

Procedure

3-(4-Mercaptophenyl)propanoic acid (5 g), K2CO3 (11.4 g) and DMF (30 ml) were combined, and iodomethane (5.12 ml) was added dropwise to the mixture at 0° C. under N2 atmosphere. The reaction mixture was stirred at r.t. for 13 hours, and poured into ice-water. The mixture was extracted with AcOEt. The organic layer was washed with water (twice) and brine, dried over anhydrous MgSO4, and concentrated in vacuo to give methyl 3-[4-(methylthio)phenyl]propanoate (4.19 g) as pale yellow oil.
