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), ethyl 4-piperidinecarboxylate (38 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 quenched with water, partitioned between DCM (25 mL) and water (25 mL). The organic phase was washed with brine, dried over sodium sulphate and evaporated to afford the crude product ethyl 1-{2-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]ethyl}-4-piperidinecarboxylate (D91) (60 mg). MS (ES): C30H35ClN4O4 requires 550; found 551.3 (M+H+).
