実験手順

Ethylmagnesium bromide (3 M in Et2O, 0.064 mL, 0.193 mmol) was added dropwise to a solution of 5-bromo-1-methyl-1H-imidazole (31.0 mg, 0.193 mmol) in DCM (1 mL) under a nitrogen atmosphere. The mixture was stirred at room temperature for 15 minutes, then was cooled to 0° C. A solution of (2,4-dichloro-3-phenylquinolin-6-yl)(3-methylisoxazol-5-yl)methanone (49.2 mg, 0.128 mmol, Intermediate 3: step b) in DCM (2 mL) was added via cannula. The mixture was stirred at room temperature for 2 hours. The reaction was quenched by addition of saturated aqueous NH4Cl and was diluted with water. The mixture was extracted three times with EtOAc. The organic phase was dried (Na2SO4), filtered, and concentrated to dryness. The crude product was purified by RP-HPLC (10-90% CH3CN—H2O, 0.1% TFA) to afford the title compound along with the intended product (2,4-dichloro-3-phenylquinolin-6-yl)(1-methyl-1H-imidazol-5-yl)(3-methylisoxazol-5-yl)methanol. 1H NMR (400 MHz, DMSO-d6) δ 8.41 (s, 1H), 8.06 (d, J=9.05 Hz, 1H), 7.92 (d, J=8.80 Hz, 1H), 7.47-7.63 (m, 3H), 7.36-7.47 (m, 2H), 6.53 (br. s., 1H), 6.34 (s, 1H), 2.23-2.38 (m, 2H), 2.20 (s, 3H), 0.76 (t, J=7.21 Hz, 3H); MS m/e 413.1 (M+H)+.
