To a solution of {5-[(2-Chloro-pyrimidin-4-yl)-methyl-amino]-1-methyl-1H-benzoimidazol-2-yl}-(4-methoxy-phenyl)-carbamic acid tert-butyl ester (100 mg, 0.20 mmol) and 4-[(methylsulfonyl)methyl]aniline (37 mg, 0.20 mmol) was added cat HCl and the reaction was heated to 70 C overnight. The reaction was neutralized with solid NaHCO3, filtered and concentrated. The crude material as purified through silica gel to give the title compound as a white solid. 1H NMR (300 MHz, d6-DMSO) δ 9.24 (s, 1H), 7.82 (d, J=6.0 Hz, 1H), 7.65-7.74 (m, 3H), 7.54 (d, J=1.5 Hz, 1H), 7.35 (d, J=8.7 Hz, 2H), 7.24 (dd, J=8.7 and 1.5 Hz, 1H), 7.18 (d, J=8.4 Hz, 2H), 6.94 (d, J=9.0 Hz, 2H), 5.72 (d, J=5.7 Hz, 1H), 4.32 (s, 2H), 3.78 (s, 3H), 3.74 (s, 3H), 3.46 (s, 3H), 2.84 (s, 3H), 1.41 (s, 9H). MS (ESI) m/z=644 [M+H]+.
