실험 절차

To a stirred solution of [7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]acetaldehyde (D88) (50 mg), 1-aminocyclopropanecarboxylic acid (25 mg) and acetic acid (0.1 mL) in DCM (10 mL) was added sodium triacetoxyborohydride (52 mg). The reaction was stirred at 20° C. for 3 h. The mixture was concentrated and the residue was partitioned between ethyl acetate (25 mL) and aqueous HCl (2 M, 25 mL). The organic phase was washed with water (25 mL) and brine (25 mL), dried over anhydrous sodium sulphate and evaporated to give the crude product, which was purified by Mass Directed Auto Prep to afford 1-({2-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]ethyl}amino)cyclopropanecarboxylic acid (E68) (8 mg, TFA salt). δH (DMSO-d6, 400 MHz): 1.36 (6H, d), 1.41 (4H, m), 3.06 (2H, t), 3.31 (2H, t), 3.65 (3H, s), 4.88 (1H, m), 7.22 (1H, t), 7.33 (1H, s), 7.46 (2H, m), 7.81 (1H, dd), 8.12 (1H, dd), 8.19 (1H, d). MS (ES): C26H27ClN4O4 requires 494; found 495.2 (M+H+).
