The product of step (v) (175 mg), the product of step (vi) (124 mg) and potassium carbonate (133 mg) in acetonitrile (10 ml) were charged to a flask and stirred at 65° C. overnight. The reaction mixture was cooled, diluted with water (20 ml) and extracted with diethyl ether. The combined organic extracts were washed with brine, dried (MgSO4) and concentrated under reduced pressure. The residue was purified by chromatography on silica eluting with isohexane then 4:1 isohexane/ethyl acetate to give the sub-title compound as a colourless oil, yield 121 mg.
