1-(2-Bromophenyl)ethan-1-ol → (1S)-1-(2-iodophenyl)ethanol

Temperatur

150 °C

To each of three identical Emrys microwave reaction vessels was added (S)-1-(2-bromophenyl)ethanol (1.67 g, 8.3 mmol), CuI (189 mg, 1.0 mmol), 1,4-dioxane (12.4 ml), N,N′-dimethylethylenediamine (0.18 ml, 1.7 mmol) and sodium iodide dihydrate (3.1 g, 16.6 mmol). Each vessel was sealed and heated in an Emrys microwave reactor to 150° C. for 2 h. On cooling, the mixtures were combined and partitioned between water (20 ml) and EtOAc (20 ml). The organic phase was washed with brine (20 ml), dried (MgSO4), filtered, and concentrated in vacuo. The crude product was taken up in isohexane (50 ml) and the solution held at −15° C. for 16 h to afford (S)-1-(2-iodophenyl)ethanol as a white crystalline solid (4.95 g).
