To a solution of [3-(5-benzyl-4-oxo-4,5-dihydro-3H-imidazo[4,5-c]pyridin-2-yl)-cyclohexyl]-carbamic acid benzyl ester (0.1 g, 0.22 mmol) in DMF (3 mL) were added Cs2CO3 (0.14 g, 0.44 mmol) and a solution of 2-cyanobenzyl bromide (52 mg, 0.26 mmol) in 3 mL DMF. After stirring for 17 h at room temperature, the reaction mixture was diluted with water (10 mL) and extracted with CH2Cl2. The combined extracts were dried over MgSO4, and concentrated in vacuo. The crude product was purified by flash chromatography, eluting with 1% MeOH in CH2Cl2 to give {3-[5-benzyl-3-(2-cyano-benzyl)-4-oxo-4,5-dihydro-3H-imidazo[4,5-c]pyridin-2-yl]-cyclohexyl}-carbamic acid benzyl ester (83 mg, 66% yield). 1H-NMR (CDCl3): δ 7.73 (m, 1H), 7.48 (m, 1H), 7.32 (m, 1H), 7.15 (d, 1H, J=7.2 Hz), 6.90 (d, 1H, J=8.0 Hz), 6.68 (d, 1H, J=7.6 Hz), 6.21 (m, 1H), 5.92 (m, 1H), 5.05 (s, 2H), 4.70 (m, 1H), 3.58 (m, 1H), 2.80 (m, 1H), 2.01 (m, 2H), 1.85 (m, 1H), 1.70 (m, 2H), 1.51 (m, 2H), 1.17 (m, 1H). MS: calculated for C35H33N5O3+H 572.3; found: 572.5.
