60 mg (0.143 mmol) of N-[1-(5-chloro-1H-benzimidazol-2-yl)ethyl]-3-ethynyl-4-(pyrrolidin-1-ylcarbonyl)benzamide is dissolved in 6.0 mL dioxane/water (1:1), combined with 8.0 mg platinum/activated charcoal and hydrogenated for 7 hours with hydrogen (3 bar). Then the catalyst is filtered off and the solvent is distilled off. Yield: 99%; Rf value: 0.15 (Reversed-phase-8; methanol/5%-NaCl solution=3:2); C23H25ClN4O2 (424.93); mass spectrum: (M−H)-=423/425 (chlorine isotope) and (M+H)+=425/427 (chlorine isotope).
