実験手順
The product of step (c) was dissolved in ethanol (10 ml) and 10% NaOH (aq) (10 ml) was added and stirred for 1 h. The reaction mixture was then acidified with HCl (aq), and extracted with EtOAc. Purification by solid phase extraction using NH2 sorbent (2 g), eluting with acetonitrile followed by 10% acetic acid/acetonitrile, gave the title compound (0.301 g).
