実験手順

A mixture of 6-((5-bromo-1H-benzo[d]imidazol-1-yl)methyl)-2-(methyl sulfinyl)benzo[d]oxazole (206 mg, 0.53 mmol), (1R,2R)-2-aminocyclohexanol (91 mg, 0.79 mmol) and DIEA (136 mg, 1.06 mmol) in DMA (4 mL) was stirred at 120° C. for 2 h. The reaction mixture was cooled to rt, poured into water (30 mL) and extracted with ethyl acetate (30 mL×3). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by preparative HPLC to give (1R,2R)-2-((6-((5-bromo-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]oxazol-2-yl)amino)cyclohexanol as a light yellow solid (175 mg, 74.8%). 1H NMR (300 MHz, DMSO-d6) δ 8.46 (s, 1H), 7.81-7.84 (m, 2H), 7.56 (d, J=8.7 Hz, 1H), 7.33-7.36 (s, 1H), 7.12 (s, 2H), 5.48 (s, 1H), 4.68 (d, J=4.2 Hz, 1H), 3.35 (br s, 2H), 1.90 (br s, 2H), 1.62 (br s, 2H), 1.22 (br s, 4H). LCMS (ESI) m/z 442 (M+H)+.
