3-[4″-(cyanomethoxy)-2,3″-diisobutyl-3′-isopropyl-1,1′:4′,1″-terphenyl-4-yl]propanenitrile (8f) (19.0 mg, 0.038 mmol) was dissolved in 5 ml of EtOH containing 10% Pd/C (15 mg) and 0.1 ml HCl (cone.). The solution was stirred overnight under 20 psi of H2. The reaction mixture was filtered through celite and the filtrate was concentrated in vacuo to yield 20 mg of a white solid (91%): 1H NMR (500 MHz, CD3OD) δ 0.75 (d, J=6.6 Hz, 6H), 0.93 (d, J=6.9 Hz, 6H), 1.14 (d, J=6.9, 6H), 1.68 (m, 2H), 1.96 (m, 1H), 1.99 (m, 1H), 2.54 (d, J=6.6 Hz, 2H), 2.62 (d, J=6.9 Hz, 2H), 2.76 (t, J=7.4, 2H), 2.96 (t, J=6.8 Hz, 2H), 3.11 (m, 1H), 3.41 (t, J=4.5 Hz, 2H), 4.29 (t, J=5.0 Hz, 2H), 7.13 (m, 9H); 13C NMR (125 MHz, CD3OD) δ 22.85, 22.96, 24.61, 30.15, 30.53, 30.54, 30.81, 33.34, 40.12, 40.53, 40.70, 43.42, 66.06, 112.90, 126.84, 127.50, 127.67, 129.06, 130.75, 131.25, 131.29, 131.33, 133.29, 136.26, 140.46, 140.49, 140.59, 141.95, 142.56, 147.13, 156.52; HRMS (FAB, M+H) Calcd for C34H49N2O: 501.3845. Found 501.3845.
