Imidazole → (3-Iodomethyl-phenoxy)-acetic acid methyl ester

Participants

Reaction Steps

Dichloromethane (85 mL) was added to Ph3P (4.942 g, 18.8 mmol), imidazole (1.311 g, 19.3 mmol) and I2 (4.735 g, 18.7 mmol). The mixture was stirred for 5 min. and then a solution of 12-2 (2.937 g, 15.0 mmol) in 15 mL dichloromethane was added by cannula. The reaction was stirred for 3 h, silica gel was added and the mixture evaporated. The residue was purified by flash chromatography on silica gel (10%→20%→30% ethyl acetate/hexanes) to give 12-3 (4.246 g, 13.9 mmol, 93%).
