Procedure

A solution of the product from step (iii) (0.7 g) in THF (10 mL) was added to a solution of lithium aluminium hydride (1M in THF, 4.1 mL) in THF (10 mL) at 0° C. The mixture was stirred at rt for 2 h, sodium sulfate decahydrate (10 g) was added and the suspension stirred for 1 h. The suspension was filtered and the filtrate diluted with saturated aq ammonium chloride (20 mL). The aqueous phase was separated and the organic phase dried and evaporated under reduced pressure to give the subtitle compound 0.60 g, which was used without further purification.
