5-[1-(3-Phenyl-allyl)-1H-imidazol-4-yl]-4-(7-phenyl-heptanoylamino)-pent-2-enoic acid ethyl ester → 4-(7-Phenyl-heptanoylamino)-5-[1-(3-phenyl-propyl)-1H-imidazol-4-yl]-pentanoic acid ethyl ester

Participants

Reaction Steps

A solution of 5-[1-(3-phenyl-allyl)-1H-imidazol-4-yl]-4-(7-phenyl-heptanoylamino)-pent-2-enoic acid ethyl ester (110 mg, 0.21 mmol) and Pd/C (50 mg) in ethanol (100 mL) was subject to hydrogenation (42 psi) for 2 hr. The solution was filtered and the solvent removed. The residue, ESMS 518 (M+H+) was hydrolysed directly without characterisation.
