Procedure

The compound of step 2 (0.128 g, 0.435 mmol) was dissolved in 2 ml of THF and cautiously added to an ice-cold suspension of lithium aluminium hydride (174 mg, 4.35 mmol) in THF. After a few minutes, diethyl ether (12 ml) was added and thereafter 200 μl of EA. Subsequently, water was added slowly and cautiously until the alumina salts formed a light grey mass at the bottom of the flask. The supernatant was decanted and the residue washed with EA. The combined extracts were dried over sodium sulfate and evaporated to dryness. The residue was used in the next step without further purification.
