Reaction Steps

The acetylene (EG00298/5-Guanidino-2-{[3-(3-pyridin-3-ylethynyl-benzenesulfonyl amino)-thiophene-2-carbonyl]-amino}-pentanoic acid; approx 10 mg) was dissolved in tetrahydrofuran:water (4:1, 2 mL), palladium on charcoal (approx 10% weight) was added and a hydrogen atmosphere introduced by balloon. The reaction mixture was stirred at 20° C. for 24 hours with occasional refilling of the hydrogen balloon. After this time the reaction mixture was filtered over Celite™ and the solvent removed in vacuo. The yellow residue was purified using preparative LCMS.
