Participants

Reaction Steps

Ethanesulphonyl chloride (0.1 ml) was added to a mixture of the product from step (iii) (0.11 g) and pyridine (0.5 ml) in DCM (4 ml). After stirring at room temperature for 4 h the mixture was partitioned between diethylether/2 M HCl. The organics separated, dried and evaporated under reduced pressure. The residue was dissolved in methanol (5 ml) then 2M NaOH added and stirred at room temperature for 20 h. The solvent was removed under reduced pressure and the residue partitioned between ethylacetate/1M HCl. The organics were separated, washed with water, dried and evaporated under reduced pressure. The residue was purified by chromatography on silica eluting with 80% ethylacetate/isohexane, yield 0.025 g.
