Reaction Steps

To a stirred solution of 6-chloropyridine-2,3-diamine(8-1, Oguchi, et. al. J. Med. Chem. (2000), 43, 3052-3066; 15 g, 105 mmol) in DMF (53 mL) was added ethyl oxo(phenyl)acetate (23 mL, 160 mmol) and DIPEA (37 ml, 210 mmol). After 72 hours, the reaction was concentrated to dryness. The resulting material was suspended in ethyl acetate/water and filtered to give 8-2 as a solid. The organic phase was washed with water, NaHCO3 and brine, dried over sodium sulfate, filtered and concentrated. The crude mixture was suspended in DCM (200 mL) and filtered to give another batch of 8-2 as a solid. MS calculated: 257.7; observed: 258.0.
