Diphosgene (0.22 mL, 1.82 mmol) was added to a mixture of 5 (726 mg, 1.52 mmol) and DMAP (557 mg, 4.56 mmol) in dry DCM (25 mL) at r.t. under nitrogen. After 30 mins a solution of 6 (2.60 g, 12.9 mmol; freshly made by the procedure mentioned above – no number previously assigned to alcohol) in dry DCM (25 mL) was added and the mixture stirred at r.t. overnight. After 18 h the reaction mixture was washed with H2O (1 x), dried (Na2SO4) and solvent removed under vacuum.
