Versuchsvorschrift

[3-(2-Bromomethyl-4-nitro-phenoxy)-4-methoxy-phenyl]-acetic acid ethyl ester (0.4 g, 0.94 mmol), 2-propanethiol (0.11 mL, 1.13 mmol), and sodium hydride (60% in mineral oil; 0.05 g, 1.13 mmol) were combined in 1,4-dioxane and stirred at room temperature for 30 minutes. The mixture was worked-up to give [3-(2-isopropylsulfanylmethyl-4-nitro-phenoxy)-4-methoxy-phenyl]-acetic acid ethyl ester, which was then reduced to the amine as described in Example 3, Step 5 to provide [3-(4-amino-2-isopropylsulfanylmethyl-phenoxy)-4-methoxy-phenyl]-acetic acid ethyl ester The amine was then treated with pivaloyl chloride according to Example 3, Step 6 to provide {3-[4-(2,2-dimethyl-propionylamino)-2-isopropylsulfanylmethyl-phenoxy]-4-methoxy-phenyl}-acetic acid ethyl ester. Hydrolysis of the ester according to the procedure described in Example 3, Step 7 provided the acid.
