実験手順
Ethyl 2-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)-2-hydroxypropylthio]benzimidazole-5-carboxylate was prepared in a similar manner to Example 2 with 3-(4-acetyl-3-hydroxy-2-propylphenoxy)-1,2-epoxypropane (1.91 g) and ethyl 2-mercaptobenzimidazole-5-carboxylate (1.70 g). 2.10 g (58.1%) of the esters was obtained as a yellow oil. This ester (2.10 g) was converted to the title compound (870 mg. 44.1%) as pale brown crystals in the same manner as Example 2, mp 133-135° C.
