Procedure
A solution of iodine (11.92 g) in DCM (300 mL) was added to a stirred mixture of the product from step (i) (8.3 g) and sodium hydroxide (3.42 g) in water (200 mL). The reaction mixture was stirred at rt overnight. The organic layer was separated and washed with sodium metabisulfate solution, then brine. The combined organic layers were dried, and the solvent evaporated under reduced pressure. The product was purified by chromatography eluting with DCM:MeOH; 95:5 to give the subtitle compound 11 g.
