Participants

Reaction Steps

324 mg (0.61 mmol) of 2-{4-[4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid ethyl ester and 1.83 ml 1N LiOH in 3 ml terahydrofurane were stirred over night at RT. The reaction mixture was taken up in ether and washed with 1N HCl and water. The crude product was suspended in AcOEt/heptane 1:19. The resulting crystals were filtered off providing 282 mg pure 2-{4-[4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid.
