反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In analogy to the procedure described in example 14 b], [rac]-2-ethoxy-3-(3-fluoro-4-hydroxy-phenyl)-propionic acid ethyl ester (example 7 a]) was reacted with 4-chloromethyl-2-p-tolyl-thiazole (prepared from 4 methyl-thiobenzamide and 1,3-dichloroacetone in analogy to the procedure described in example 4 a]) in the presence of cesium carbonate and potassium iodide to yield [rac]-2-ethoxy-3-[3-fluoro-4-(2-p-tolyl-thiazol-4-ylmethoxy)-phenyl]-propionic acid ethyl ester, which was further saponified in analogy to the procedure described in example 4 e], to yield [rac]-2-ethoxy-3-[3-fluoro-4-(2-p-tolyl-thiazol-4-ylmethoxy)-phenyl]-propionic acid as light yellow solid.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2-Methylthiobenzamide in an amount of 1.67 g is suspended in 25 ml of dry xylene. After addition of 1.54 g of 4-chlorophenylisocyanate, the reaction mixture is refluxed over night. After cooling to room temperature the desired product crystallizes in a yield of 2.8 g, m.p. 211° C. The same result is obtained when 2-methylthiobenzoyl isocyanate is reacted with 4-chloroaniline. the reaction mixture is refluxed over night
