실험 절차

A 25-mL round bottom flask was charged with ethyl 2-(4-((2-(3-chlorophenyl)-6-cyclopropylpyridin-4-yl)amino)phenyl)acetate (0.152 g, 0.37 mmol) and THF (6 mL) at rt. Borane-dimethylsulfide complex (0.106 mL, 1.12 mmol) was added and the resulting solution was stirred at 50° C. for 2.5 h until the starting material was consumed (monitored by LCMS analysis). The reaction was quenched with methanol then treated with 2N aqueous HCl (5 drops) and concentrated under reduced pressure. The residue was diluted with methanol and then concentrated under reduced pressure. The residue was treated with saturated sodium bicarbonate (0.1 mL) and then purified by column chromatography on silica using hexanes/ethyl acetate (10:0 to 0:10) as the eluent to afford 2-(4-((2-(3-chlorophenyl)-6-cyclopropylpyridin-4-yl)amino)phenyl)ethanol (0.107 g, 78%) as a colorless oil. MW=364.87. 1H NMR (CDCl3, 500 MHz) δ 7.94-7.92 (m, 1H), 7.81-7.76 (m, 1H), 7.35-7.30 (m, 2H), 7.27-7.23 (m, 2H), 7.18-7.14 (m, 2H), 6.99 (d, J=2.0 Hz, 1H), 6.65 (d, J=2.0 Hz, 1H), 5.94 (s, 1H), 3.90 (q, J=6.0 Hz, 2H), 2.88 (t, J=1.5 Hz, 2H), 1.99-1.92 (m, 1H), 1.40 (t, J=2.0 Hz, 1H), 1.12-1.07 (m, 2H), 0.96-0.90 (m, 2H); ESI MS m/z 365 [M+H]+. Treatment with 1.25M HCl in methanol (0.70 mL, 0.88 mmol) afforded the title compound (0.105 g, 90%) as a light yellow solid. MW=401.33. M.p. 125-128° C. 1H NMR (DMSO-d6, 500 MHz) δ 13.57 (br s, 1H), 10.50 (br s, 1H), 7.95-7.93 (m, 1H), 7.77-7.73 (m, 1H), 7.72-7.66 (m, 1H), 7.65-7.59 (m, 1H), 7.34-7.29 (m, 2H), 7.28-7.24 (m, 2H), 7.07 (s, 1H), 6.58 (br s, 1H), 3.63 (t, J=7.0 Hz, 2H), 2.74 (t, J=7.0 Hz, 2H), 2.40-2.29 (m, 1H), 1.22 (s, 2H), 1.05-0.96 (m, 2H); APCI MS m/z 365 [M+H]+.
