Procedure

200 mg (0.384 mmol) of N—((S)-2-diphenylamino-1-hydrazinocarbonylethyl)-2-(2-methylaminopyrimidin-4-yl)-1H-indole-5-carboxamide (27) were suspended in 20 ml of methylene chloride, and a 20% solution of phosgene in toluene (0.398 mmol) was added dropwise at 0° C. and while stirring. The mixture was stirred at room temperature for a further 15 h and the solvent was evaporated. The oxadiazolone 28 was then isolated by flash chromatography on silica gel (DCM:MeOH=9:1). Yield: 160 mg (76%)
