Reaction Steps

A suspension of 10% Pd/C (0.20 g) and N-benzyloxy-N-methyl-1-[4-(5-fluoroindol-3-yl)piperidine-1-sulfonyl]piperdine-2-(R)-carboxamide (0.40 g, 0.75 mmol) [prepared as described in Step 4 above] in 80% ethanol/tetrahydrofuran (6 ml) was stirred under a hydrogen atmosphere (1 atm) for 70 min. The reaction was degassed with nitrogen, filtered through Celite and the filtrate was concentrated in vacuo. The residue was chromatographed (PTLC, SiO2, 10% methanol/methylene chloride) to give N-hydroxy-N-methyl-1-[4-(5-fluoroindol-3-yl)piperidine-1-sulfonyl]piperidine-2-(R)-carboxamide (83%) as a white solid.
