Tetrahydrofuran → HCID 178520841, compound

Participants

Reaction Steps

To a solution of N-nicotinoyl-β-alanyl-(L)-histidine (9.9 g, 30.1 mmoles) in tetrahydrofuran (200 ml) triphenylphosphine (23.7 g, 90.3 mmoles) and carbon tetrabromide (28.85 g, 90.3 moles) are added under stirring. The reaction mixture is left under stirring at room temperature for 24 hours. Lastly the solvent is removed by evaporation at reduced pressure. The obtained crude product is purified by chromatography on silica gel column eluting with n-hexane/ethyle acetate 1/1. N-nicotinoyl-β-alanyl-(L)-histidine 4-bromobutyl ester is obtained.
