Reaction Steps

To 2-Iodo-5-methanesulfonyl-benzoic acid (Example C, 10.0 g, 30.7 mmolin 250 ml THF was added CDI (5.50 g, 33.7 mmol) and the mixture heated at 70° C. for 1 h. Methanol (12.4 ml, 307 mmol) was then added and the mixture was heated at 70° C. for a further 1 h. The mixture was then cooled to room temperature and concentrated in vacuo. The residue was chromatographed over SiO2 (ethyl acetate/dichloromethane 4:1) to afford the title compound (8.95 g, 86%) as white crystalline solid.
