実験手順

The product of step c) (0.11 g) was dissolved in DMF (5 ml), ethylbromoacetate (0.04 ml) and potassium carbonate (0.1 g) were added. The reaction mixture was stirred for 16 h at RT. Water and ethyl acetate were added. The organic layer was removed, dried (MgSO4) and evaporated in vacuo. The residue was purified by flash column chromatography eluting with isohexane:ethyl acetate (1:1) to give the sub-title compound. Yield 0.12 g.
