Participants

Reaction Steps

6-Amino-3-(4-pyridyl)-2-(4-fluorophenyl)-7-aza-indole (17) (100 mg, 0.329 mmol), benzaldehyde (100 ml, 0.987 mmol), and 1,2-dichloroethane (20 mL) were allowed to stir for 15 min followed by the addition of sodium triacetoxyborohydride (139 mg, 0.658 mmol) as a solid. After 16 h at 23° C., the reaction was partitioned between ethyl acetate (200 mL) and satd bicarbonate (80 mL). The organic layer was washed with brine (80 mL), and dried (Na2SO4). After concentration in vacuo, a portion of the residue was purified by preparative chromatography to afford 6-(phenylmethylamino)-3-(4-pyridyl)-2-(4-fluoro phenyl)-7-aza-indole (144):Mass Spectrum (CI) 395 (MH+).
