Procedure

To a solution of the alcohol of Step 3 (2.87 g, 11.8 mmol) and the acid from step 1 (2.0 g, 15.4 mmol) in CH2Cl2 (30 mL) was added CMC (7.5 g, 17.7 mmol), along with 50 mg of DMAP. After stirring overnight, H2O (20 mL) was ad ded and the product was extracted with CH2Cl2. The organic layer was dried (MgSO4), filtered and evaporated. Purification was effected by flash chromatography (1:5 EtOAc:hexane) to yield 2.97 g of an oil.
