To a solution of (2.65 mmol) of the ester from step C in 25 ml of EtOH is added 10 ml (10.0 mmol, 3.75 equiv) of 1N NaOH. The mixture is stirred for 1 hour at room temperature which time the mixture is acidified to pH~4 using 1N HCl. A precipitate forms which is filtered off and recrystallized from hot MeOH-Et2O to afford 2-(2-(3-((quinolin-2-yl)methyloxy)phenoxymethyl)phenoxy)propionic acid.
