Versuchsvorschrift

The product from step (iii) (12 g) was dissolved in THF (120 mL) and borane-tetrahydrofuran complex (1M in THF, 132.3 ml) added dropwise. The reaction mixture was stirred at rt overnight then MeOH was added followed by 2M HCl (20 mL). The mixture was evaporated and the residue taken up in MeOH and purified via SCX resin and the residue was further purified via column chromatography eluting with 10-20% EtOAc in isohexane to give the subtitle compound 6 g.
