To a solution of 1,3-phenylenediacetonitrile (9.37 g, 60 mmol) in CH3OH (saturated with NH3, 150 mL) was added Raney-Ni (ca. 20 g, previously washed with CH3OH several times) and the mixture was hydrogenated at 45 psi on a Parr apparatus for 48 h. The reaction mixture was filtered through celite and the filtrate evaporated to give the crude product (9.45 g, 96%) as a light green oil: 1H NMR (CDCl3) δ 0.80-1.50 (br s, 4H), 2.70-2.76 (m, 4H), 2.94-2.99 (m, 4H), 7.01-7.07 (m, 3H), 7.18-7.26 (m, 1H). This was used in the next step without further purification.
