実験手順
(Z)-Methyl 3-(furan-3-yl)-2-methoxy-6-((2-(3-(piperidin-1-yl)prop-1-enyl)benzenesulfonyl)methyl)benzoate (Intermediate 198, 0.069 g) was added to a solution of lithium hydroxide monohydrate (0.051 g) in water (0.7 ml) and dioxane (3 ml) and the resultant mixture was stirred and heated at 65° C. for 4 days. After cooling, the mixture was diluted with water and washed with diethyl ether. The aqueous layer was acidified with 1M HCl and extracted with ethyl acetate, washed with brine, dried (Na2SO4) and filtered. The filtrate was evaporated to dryness and the residue was purified by HPLC (C6 phenyl column) eluting with 1:1 methanol:water containing 0.1% formic acid to give (Z)-3-(Furan-3-yl)-2-methoxy-6-((2-(3-(piperidin-1-yl)prop-1-enyl)benzenesulfonyl)methyl)benzoic acid as a white solid.
