Reaction Conditions

Reaction Steps

To a mixture of N,N dimethylaminoethanol in DMSO (1 mL) was added NaH (60% dispersion in mineral oil, 0.019 g, 0.481 mmol). The mixture was heated to 50° C. for 15 min. After cooling, 2-Chloro-6-(4-{[4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl]methyl}phenyl]-5-phenylnicotinonitrile (2-6, 0.050 g, 0.096 mmol) was added and the reaction was allowed to stir for 16 hr at rt. The resulting mixture was diluted with water (10 mL) and the resulting precipitate was filtered. The filtered cake was purified by reverse phase HPLC. (5% CH3CN: 95% H2O+0.01% TFA to 95% CH3CN: 5% H2O+0.01% TFA). 1H-NMR (500 MHz, d6 DMSO) δ 10.93 (s, 1H), 9.86 (bs, 2H), 8.45 (s, 1H), 7.40-7.55 (m, 4H), 7.25-7.40 (m, 6H), 7.00 (d, J=2.93, 3H), 4.85 (t, J=4.89, 2H), 4.45 -4.55 (m, 1H), 4.34 (s, 2H), 3.64 (bs, 2H), 3.46 (d, J=11.72, 2H), 3.10-3.25 (m, 2H), 2.94 (d, J=4.15, 6H), 2.56-2.69 (m, 2H), 1.93, (d, J=12.00, 2H).
