Participants

Reaction Steps

A mixture of 3-(4-iodo-phenoxy)-5-(1-methyl-1H-imidazol-2-ylsulfanyl)-benzoic acid (1.4 g, 3.1 mmol), K2CO3 (856 mg, 6.2 mmol), iodomethane (0.29 mL, 4.65 mmol) and 16 mL of DMF were stirred for 2 h at rt. Then the mixture was diluted with ether and washed with water, brine, dried (MgSO4) and evaporated. The residue was adsorbed to SiO2 from CH2Cl2 and subjected to MPLC on a 40 g column of SiO2 eluting with % EtOAc in hexanes (time): 33% (10 min), 35-50% (20 min ramp) which provided 1.32 g (91%) of the title compound: 1H NMR (500 MHz, DMSO-d6): δ 3.63 (s, 3H), 3.79 (s, 3H), 6.91 (d, 21-1, J=8 Hz), 6.96 (dd, 1H, J=2, 1 Hz), 7.14 (d, 1H, J=1 Hz), 7.23 (dd, 1H, J=2, 1 Hz), 7.32 (t, 1H, J=1 Hz), 7.51 (d, 1H, J=1 Hz), 7.75 (d, 2H, J=8 Hz); LCMS (m/z): 467.4 [C18H15IN2O3S+H]+.
