Reaction Steps

A mixture of methyl(5R)-3-[(2R)-2,3-dihydro-1-[(phenylmethoxy)acetyl]-2-methyl-1H-indol-5-yl]-2-oxo-5-oxazolidinecarboxylate (Step 1, 0.301 g, 0.71 mmol) and Pearlman's catalyst (0.032 g) in methanol (30 mL) is shaken on a Parr apparatus under a 36 psi hydrogen atmosphere for approximately 24 h, during which additional Pearlman's catalyst (0.044 g) is added. The catalyst is removed by filtration through a pad of Celite, and the filtrate is concentrated under reduced pressure. The residue is purified by chromatography on a Biotage Flash 40S silica gel cartridge (2% MeOH(CH2Cl2 eluent) to give the title compound, MS (ESI+) for C16H18N2O6 M/Z 335 (M+H)+.
