실험 절차

The product from step (a) (1.0 g) was dissolved in a 2:1 water:methanol mixture (15 ml) and lithium hydroxide monohydrate added. After 2 hours 2M aqueous hydrochloric acid and ethyl acetate were added, the organic phase separated, dried and concentrated to give the product as a solid (1.2 g), m.p. 141-142° C.
