Participants

Conditions

Temperature: 80 °C

Procedure

A vial was charged with methyl 6-chloro-5-[6-(3-hydroxypyrrolidin-1-yl)-2-methoxypyridin-3-yl]-1H-indole-3-carboxylate (52.5 mg, 0.130 mmol), NaOH aqueous (2 mL, 2M) and methanol (2 mL). The mixture was heated at 80° C. for 3 hrs. The mixture was cooled to room temperature and neutralized with conc. HCl aqueous to pH=6. The mixture was evaporated to dryness, and the resulting residue was purified through prep. HPLC to give the title compound (18.9 mg, 37.3%) as off-white solid.
