Reaction Steps

8-{(E)-2-[4-((R)-2-Hydroxymethyl-5-oxo-pyrrolidin-1-yl)-2-methyl-phenyl]-ethenesulfonyl}-2-(3-trifluoromethyl-phenyl)-1,3,8-triaza-spiro[4.5]dec-1-en-4-one (28.5 mg, 48.3 μmol) was dissolved in EtOH/DMF 4:1 (concentration 10 mg/ml). The mixture was allowed to pass through 10% Pd/C (CatCart™) at a flow rate of 2 ml/min under the conditions of 30 bar and 40° C. in a hydrogen atmosphere, and was subjected to hydrogenation reaction. The resulting reaction solution was concentrated under reduced pressure. The residue was purified by preparative TLC(CH2Cl2/MeOH=20:1) to give 8-{2-[4-((R)-2-hydroxymethyl-5-oxo-pyrrolidin-1-yl)-2-methyl-phenyl]-ethanesulfonyl}-2-(3-trifluoromethyl-phenyl)-1,3,8-triaza-spiro[4.5]dec-1-en-4-one as a white powder (12.9 mg, 45%).
