Procedure

A solution of ((1S,2S,3R,4R)-2-(3-(benzyloxy)benzyl)-4-(tert-butyldimethylsilyoxy)-3-((S,E)-3-(tert-butyldimethylsilyoxy)oct-1-enyl)cyclopentyl)methyl methanesulfonate (45 g, 0.06 mol) in dry methanol (450 ml) was treated with potassium hydroxide (9.72 g, 0.18 mol), then with 5% Pd/C (13.5 g, 30% wt) under hydrogen for 2 hr. Then, the reaction mixture was filtered with celite pad. The filtrate was concentrated to obtain crude product (50 g).
