Procedure
In analogy to Example 14, 2-ethyl-4-[5-(2-isobutyl-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-6-methyl-phenol is alkylated with epichlorhydrine to give (RS)-4-[3-(3-ethyl-5-methyl-4-oxiranylmethoxy-phenyl)-[1,2,4]oxadiazol-5-yl]-2-isobutyl-6-methyl-pyridine as a colourless oil; LC-MS: tR=1.00 min, [M+1]+=408.18.
