実験手順

An aqueous solution of sodium hydroxyde (2N, 75 ml) was added at room temperature to a solution of 2-{[4-(1,3-benzodioxol-5-yl)-1-benzyl-5-(bis{[4-(tert-butyl)phenyl]sulfonyl)amino)-1H-pyrazol-3-yl]oxy}ethyl acetate (Preparation 52) (24 g) in ethanol (300 ml) and left overnight. The reaction mixture was then diluted with water (1000 ml), acidified with an aqueous solution of HCl (1N) and extracted with ethyl acetate (3×500 ml). The combined organic phases were washed with brine (500 ml) and concentrated under reduced pressure. The yellow oil was purified by column chromatography (silica, 500 g) eluted with hexane:ethyl acetate (1:1) yielding the title compound as a pale beige solid (16 g).
