실험 절차

A mixture of the product from step (iii) (0.3 g), tert-butylbromoacetate (0.15 ml) and potassium carbonate (0.13 g) in DMF (20 ml) was stirred at RT overnight. The mixture was partitioned between water and ethylacetate, the organics separated, dried, and evaporated under reduced pressure. Yield 0.55 g
