Participants

Reaction Steps

(±)-cis-N1-[(5-chloroindol-2-yl)carbonyl]-N2-[(4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)-carbonyl]-1,2-cyclohexanediamine hydrochloride (100 mg) was dissolved in pyridine (3 ml), triethylamine (168 μl) and methanesulfonyl chloride (48 μl) were added, and the mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and dichloromethane and 1N hydrochloric acid were added to the residue to separate an organic layer. The resultant organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by column chromatography on silica gel (dichloromethane:methanol 100:1) to obtain the title compound (79 mg) as a pale yellow foamy substance.
