Reaction Steps

A suspension of (R)-benzyl-2-(5-(2-(phenylsulfonyl)ethyl)-1H-indole-3-carbonyl)-pyrrolidine-1-carboxylate (5.0 g) in 50 ml acetone, methanesulfonic acid, formaldehyde and 10% Pd/C was subject to hydrogenation at 45 psi. Upon completion of the reaction the catalyst was filtered off and the solvent removed under vacuum to provide the title compound in about 65-75% yield. Mass (M+Na) 419.5
