Reaction Steps

To a suspension of LAH (0.5 g, 5 eq) in THF (10 mL), was added 7a and the mixture was refluxed for 72 h. After allowing the reaction mix to cool down to room temperature, 0.5 mL of water, 1 mL of 1 M sodium hydroxide and 1.5 mL of water were added slowly and sequentially. Ethyl acetate was added and the mixture was filtered. Removal of the solvent gave 0.36 g (66% on both steps) of 7b as an oil which was used without further purification on the next step.
