Participants

Reaction Steps

A solution of 0.150 g (0.579 mmol) of 3-methyl-4-(pyrrolidin-1-ylcarbonyl)benzoic acid, 0.186 g (0.579 mmol) of TBTU, and 0.20 mL (1.78 mmol) of N-methylmorpholine in 2 mL of N,N-dimethylformamide is stirred for 10 minutes at ambient temperature and then combined with a solution of 0.158 g (0.579 mmol) of (S)-1-(5-chloro-1H-benzimidazol-2-yl)-2-pyridin-4-ylethylamine. The reaction mixture is stirred for one day at ambient temperature, then poured onto ice water and extracted three times with ethyl acetate. The combined organic phases are dried with sodium sulfate and concentrated. The residue is chromatographed on silica gel, eluting with dichloromethane/methanol (95:10). Yield: 61.5 mg (22% of theory); Rf value: 0.44 (silica gel; dichloromethane/methanol=9:1); C27H26ClN5O2 (487.99); mass spectrum: (M−H)−=486/488 (chlorine isotope).
