Procedure
To a solution of the aldehyde from Step 2 (1.0 g, 3.2 mmol) in ethanol (50 mL) and THF (20 mL) there was added cerous chloride (0.79 g, 3.2 mmol) and sodium borohydride (0.13 g, 3.5 mmol). The mixture was stirred at room temperature for 30 minutes, there was added acetone (3 mL) and after 5 minutes the mixture was diluted with brine (100 mL) and extracted with ether (100 mL). The crude material was purified by column chromatography on silica gel, eluting with a 1:5 mixture of ethyl acetate-hexane to afford the title compound as a thick yellow oil.
