To a solution of (E)-1-(5-(3,4-dichlorophenyl)furan-2-yl)prop-1-en-2-amine (2.72 g, 9.12 mmol) in MeOH (135 ml), EtOAc (100 ml) and 6.5% HCl (g) in MeOH (32 ml) was added 10% Pd/C (1.09 g). The mixture was hydrogenated under pressure (3.3 bar, Parr hydrogenating apparatus) for 7 h. The reaction mixture was filtered through Celite, evaporated and purified by chromatography (CombiFlash, silica column, eluent: 5-20% MeOH/DCM) to yield 0.811 g (29%) of the title compound as an HCl salt. 1H-NMR (400 MHz; d6-DMSO): δ 1.21 (d, 3H), 2.90 (dd, 1H), 3.04 (dd, 1H), 3.55 (q, 1H), 6.44 (d, 1H), 7.09 (d, 1H), 7.68 (m, 2H), 7.93 (m, 1H).
