The product from step (v) (Ig) was dissolved in THF (30 mL) then acetic acid (0.239 g, 0.23 ml) and methyl 2-(3-formylphenyl)acetate (0.709 g) were added followed by MeOH (0.5 mL). The reaction mixture was stirred at rt for 72 h then sodium borohydride (0.1506 g) was added. After 2 h a further portion of sodium borohydride (0.0452 g) was added and the reaction mixture stirred for 16 h. A further portion of sodium borohydride (0.1506 g) was added and stirred for 2 h. The reaction mixture was poured into saturated sodium bicarbonate solution and extracted with EtOAc. The solvents were evaporated and the product was purified by chromatography eluting with DCM:MeOH 97:3 to 80:20 to give the title compound 0.5 g.
