Versuchsvorschrift
A 5M aqueous solution of potassium hydroxide (3.10 mL) was added to a solution of the product of step (vii) (0.53 g) in MeOH (6 mL). The mixture was stirred at 65° C. for 15 h and allowed to cool. The solvent was evaporated under reduced pressure and the resulting aqueous solution adjusted to pH ˜7 with conc. HCl. The aqueous phase was extracted with DCM and EtOAc, the combined organic phase was evaporated under reduced pressure to give the subtitle compound as a colourless solid 0.547 g.
