Participants

Reaction Steps

3-Fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)benzoic acid (107 mg, 0.274 mmol) was dissolved in thionyl chloride at 65° C. for 1 h before it was concentrated. The reaction mixture was dissolved in THF (1.4 mL) before ammonium hydroxide (1.07 mL, 27.40 mmol) was added and stirred at ambient temp. for 16 h. The reaction mixture was diluted with EtOAc, added to a separatory funnel, partitioned with sodium bicarbonate (saturated, aqueous), washed with sodium bicarbonate (saturated, aqueous), separated, dried over sodium sulfate, and concentrated via rotovap to give the title compound after preparatory LC. MS (ESI) m/z: Calculated: 389; Observed: 390.1 (M++1).
