Procedure
To the product from step (ii) (4 g) in MeOH (50 ml), sodium borohydride (0.7 g) was added portionwise over 5 min. The mixture was stirred at rt for 1 h then the solvent removed under reduced pressure. The residue was partitioned between EtOAc and water, the organics were separated, dried and evaporated under reduced pressure to give the subtitle compound, 3.89 g.
