Lithium Hydroxide → 2-{4-[4-(2-Methoxy-ethyl)-6-methyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid

Participants

Reaction Steps

A solution of 244 mg (0.446 mmol) 2-{4-[4-(2-methoxy-ethyl)-6-methyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid ethyl ester and 1.34 ml 1N LiOH-solution in 2.5 ml tetrahydrofurane was stirred for 2 h at RT. The reaction mixture was taken up in ether and washed with 1N HCl and water. The crude residue was suspended in AcOEt/heptane 1:19. The resulting crystals were filtered off providing 188 mg of pure 2-{4-[4-(2-methoxy-ethyl)-6-methyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid.
