Reaction Steps

phenylmethyl (5S,7R)-8-{[{(1R)-1-[3,5-bis(trifluoromethyl)phenyl]ethyl}(methyl)amino]carbonyl}-7-(4-fluoro-2-methylphenyl)-2-oxo-1,8-diazaspiro[4.5]decane-1-carboxylate (Intermediate 33 70 mg, 0.101 mmol) was dissolved in Methanol (3 ml) and to the solution was added Pd/C (10.74 mg, 10.09 μmol) The suspension was left stirring under H2 atmosphere for 30 mins. The palladium was filtered out and the solvent removed in vacuo obtaining the title compound (53.6 mg, 0.096 mmol, 95% yield); UPLC: Rt=0.81 mins, m/z=560 [M+H]+; MS: m/z=560 [M+H]+ and 582 [M+Na]+.
