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) (20 mg), ethyl glycinate (10 mg) and acetic acid (0.1 mL) in DCM (10 mL) was added sodium triacetoxyborohydride (21 mg). The reaction was stirred at 20° C. for 1 h. The reaction mixture was partitioned between DCM (25 mL) and water (25 mL). The organic phase was evaporated to give ethyl N-{2-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]ethyl}glycinate (D89) as a brown oil (20 mg), which was used directly in the next hydrolysis step. MS (ES): C26H29ClN4O4 requires 496; found 497.2 (M+H+).
