tert-Butyl 5-(6-(1-phenylcyclopropyl)-2-thioxo-1,2-dihydropyridin-3-ylcarbamoyl)i-soindoline-2-carboxylate (213 mg, 0.437 mmol) was dissolved in toluene (4.4 mL) before camphor sulfonic acid (91 mg, 0.393 mmol) was added and stirred at 100° C. for 3 h. The reaction mixture was diluted with 75 mL of 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 2-(isoindolin-5-yl)-5-(1-phenylcyclopropyl)-thiazolo[5,4-b]pyridine after flash chromatography. MS (ESI) m/z: Calculated: 369.1; Observed: 370.4 (M++H).
