Reaction Steps

2-[(S)-1-Phenylethylamino]-4-[6-iodobenzimidazol-1-yl]pyrimidine (EXAMPLE 415) (50 mg), 1-naphthyl boronic acid (22 mg), potassium carbonate (31 mg), and tetrakis(triphenylphosphine)palladium(0) (5 mg) were dissolved in degassed n-propanol (2.6 mL) and water (0.4 mL) and stirred at 80° C. under argon atmosphere for 15 hours. Upon cooling, the reaction mixture was filtered through Celite® (the ppt was washed with 10 mL of EtOAc) and evaporated. The residue was purified by preparative thin layer chromatoraphy eluted with 5% MeOH/CH2Cl2) giving 44 mg of the title compound. 1H NMR (500 MHz, CDCl3), δ 8.82 (br s, 1H), 8.38 (s, 1H), 7.97-7.75 (m, 4H), 7.54-7.29 (m, 9H), 7.19 (t, 1 H, J=7.5 Hz), 7.01 (d, 1H, J=Hz), 5.7 (s, 1H), 1.67 (d, 3H, J=7.0 Hz); Mass spectrum (ESI) 442.3 (M+1).
