Procedure

In a 3 gallon autoclave, charge 4-(3-Cyclopent-1-enyl-indole-1-sulfonyl)-benzoic acid methyl ester (475 g), ethyl acetate (2.5 L), absolute ethanol (2.5 L) and 10% Pd—C (45 g, w/w) under 35 psi hydrogen at ambient temperature for 5 hours. Filter the crude reaction over Hyflo. Concentrate the filtrate under vacuum to give a light yellow solid (465 g) of the title compound.
