A solution of 2M sodium hydroxide (3 ml) was added to a stirred mixture of the product from step (ii) (0.36 g), water (10 ml) and THF (10 ml). After 2 h the solution was acidified with 2M hydrochloric acid and extracted with diethylether. The organics were washed with water, dried and evaporated under reduced pressure. The residue was recrystallised from diethylether/isohexane. Yield 138 mg
