Participants

Reaction Steps

A mixture of 4-(1-(2,4-dimethyl-5-(4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridin-2-yl)benzoyl)piperidin-4-yl)benzonitrile (compound 2.9, 88 mg), 1-bromo-2-fluoroethane (150 μl), potassium iodide (50 mg), and triethyl amine (140 μl) in DMF (2 ml) was stirred for 48 hours. The reaction mixture was then diluted with dichloromethane and washed with brine. The organic layer was dried (MgSO4) and concentrated. The residue was purified by prep. TLC using 8% MeOH in DCM to give 51 mg of a white solid (52%). m/z (ES+) 486 (M+H)+. 1H NMR (400 MHz, Chloroform-d) 7.63 (d, 2H), 7.32 (d, 2H), 7.28 and 7.20 (2 singlets, amide rotamers, 1H), 7.00 (s, 1H), 4.93 (m, 1H), 4.67 (dt, J1=47.6 Hz, J2=4.9 Hz, 2H), 3.71 (d, 2H), 3.62 (d, 1H), 3.03-2.71 (m, 8H), 2.43 (d, 3H), 2.29 and 2.19 (2 singlets, amide rotamers, 3H), 2.08-1.89 (m, 2H), 1.85-1.49 (m, 2H), 3.18-3.05 (m, 1H).
