Reaktionsschritte

A mixture of 3-(3-cyano-phenyl)-acrylic acid methyl ester (3.24 g, 17.31 mmol), prepared in Step B of Preparation 44, and palladium on carbon (10%, 0.600 g) in EtOAc (30 mL) was hydrogenated at 25 psi in a Parr shaker for 1h. The catalyst was removed via filtration through Celite and the solution was concentrated in vacuo. Medium pressure chromatography (6:1 hexanes:EtOAc) provided the title compound of Step A as a clear oil (2.98 g). 1H NMR (400 MHz, CDCl3) δ 7.50-7.36 (m, 4H), 3.65 (s, 3H), 2.97 (t, 2H), 2.63 (t, 2H); MS 190 (M+1).
