Reaction Steps
To a solution of methyl 2-(4′-(5-aminopyrazin-2-yl)-5′-fluorobiphenyl-2-yloxy)acetate (50 mg, 0.14 mmol) in THF (2 mL) were added LiOH.H2O (63 mg, 1.5 mmol) and H2O (2 mL). The mixture was stirred at rt for 14 hours. The THF was removed under reduced pressure, and the residue diluted with 15 mL of water, washed with DCM (5 mL×2), and then acidified with 1 N HCl to pH=7. The precipitate was collected and washed with water and dried under high vacuum to give the title compound (40 mg, 95% yield).
