実験手順

A suspension of 4-(6,7-Dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-((E)-propenyl)benzonitrile (0.150 g, 0.602 mmol), 20% (w/w) palladium on carbon (0.040 g), THE (15 mL), and EtOH (15 mL) is stirred under an atmosphere of hydrogen (1 atm) for 60 h. The suspension is the filtered and the filtrate concentrated. The residue is then purified by flash chromatography (Hexane/EtOAc, and then 10% MeOH/EtOAc) to give 4-(6,7-Dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-(n-propyl)benzonitrile as a white solid. MS (ESI) m/z 252.1 (M+H); 1H NMR (400 MHz, CDCl3) δ ppm 1.04 (t, J=7.3 Hz, 3H), 1.63-1.77 (m, 2H), 2.33-2.45 (m, 1H), 2.62-2.80 (m, 2H), 2.92 (app t, J=7.1 Hz, 2H), 3.04-3.19 (m, 1H), 5.58 (dd, J=7.8, 5.6 Hz, 1H), 6.73 (d, J=8.1 Hz, 1H), 6.81 (s, 1H), 7.25 (s, 1H), 7.41 (d, J=8.1 Hz, 1H), 7.51 (s, 1H).
