N-(tert-butoxycarbonyl)glycine → HCID 178453815, compound

Participants

Reaction Steps

11.3 mg of N-(tert-butoxycarbonyl)glycine, 25 mg HBTU and 12 μl diisopropylethylamine were taken up in 0.4 ml dimethylformamide. Reaction mixture was stirred at room temperature for one hour and 5-(4-cyclopentylaminophenylsulfonyloxy)-1H-benzimidazole-2-ylamine was added in 0.2 ml dimethylformamide. Reaction mixture was then stirred at room temperature for 24 hours. Solvent was evaporated in a Jouan model RC 10.10 centrifuge evaporator and title compound was solubilised in 0.5 ml dimethylsulfoxide for LCMS trigged purification yielding 2.4 mg of N-[5-(4-cyclopentylaminophenylsulfonyloxy)-1H-benzimidazole-2-yl]-tert-butoxycarbonylglycineamid. (LC/MS analysis: retention time=3.87 min., mass spectrum: 530.38, [M+H]+).
