The derivatives of 3-[4-(1-ethoxycarbonyl-1-methylethoxy) phenyl]-5-(3-pyridyl)-1, 2, 4-oxadiazole (I), which showed considerable hypocholesterolemic activities, were synthesized. Among them, 3-[4-(1-ethoxycarbonyl-1-methylethoxy) phenyl]-5-(2-or 3-chlorophenyl)-1, 2, 4-oxadiazole (13, 14) and their amide derivatives (29, 30) showed nearly equal activity to I. Two alternative synthetic routes of I were developed.
