Participants

Reaction Steps

Hydrazine monohydrate (55 mg, 1.1 mmol) was added to a solution of 3-benzoyl-1-(3,5-dimethyl-4-{2-[2-(4-methyl-cyclohexyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-phenyl)-1-methyl-thiourea (140 mg, 0.22 mmol) in ethanol (7 ml). The mixture was stirred at room temperature for 15 hours and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (dichloromethane-methanol) to give 1-(3,5-dimethyl-4-{2-[2-(4-methyl-cyclohexyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-phenyl)-1-methyl-thiourea (119 mg).
