Versuchsvorschrift

The product from Step 1 (0.29 g) was dissolved in propan-2-ol (5 ml) containing sodium hydroxide (0.053 g) and water (2 ml). The mixture was stirred at ambient temperature for 20 minutes, evaporated under reduced pressure to a small volume and diluted with water. The solution was acidified with dilute aqueous hydrochloric acid and extracted with ethyl acetate (three times). The extracts were combined, washed with water (three times), dried over magnesium sulphate and evaporated under reduced pressure to give the required product, 0.25 g, as a gum.
