Reaction Steps

To a solution of 4-{3-chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(5-methyl-pyrazin-2-yl)-propyl]-phenoxymethyl}-benzoic acid ethyl ester (Example 1, 130 mg, 0.26 mmol) in tetrahydrofuran (2.5 ml) and methanol (0.5 ml) was added a 1 M aqueous LiOH solution (0.31 ml). The mixture was stirred for 4 h at 60° C. (bath temperature). The cooled mixture was acidified with 1 M aqueous HCl. Tetrahydrofuran and methanol were evaporated in vacuo. To the suspension water was added. The precipitation was filtered, washed with water and dried to give the title compound as a white solid (105 mg). MS (m/e, ISP neg. ion)=479.4 [M−H+].
