(E)-3-[4-(2,3,4,5-Tetrahydro-benzo[b]azepine-1-carbonyl)-phenyl]-acrylic Acid Methyl Ester → 3-[4-(2,3,4,5-Tetrahydro-benzo[b]azepine-1-carbonyl)-phenyl]-propionic Acid Methyl Ester

Participants

Reaction Steps

(E)-3-[4-(2,3,4,5-Tetrahydro-benzo[b]azepine-1-carbonyl)-phenyl]-acrylic acid methyl ester from Example E65.2 (485 mg, 1.44 mmol) was dissolved in methanol (60 ml) and hydrogenated over 10% Pd/C catalyst (214 mg) for 2 h. The mixture was filtered through Celite® filter agent and the filtrate was concentrated in vacuo to yield the title compound (415 mg, 85%).
