Participants

Reaction Steps

To a solution of 4-[5-(5,6-diethyl-pyridin-3-yl)-[1,2,4]oxadiazol-3-yl]-2-ethyl-6-methyl-phenol (150 mg, 0.445 mmol) in isopropanol (10 mL) and 3 N aq. NaOH (3 mL), epichlorhydrine (164 mg, 1.78 mmol) is added. The mixture is stirred at rt for 20 h. The mixture is diluted with EA and washed with sat. aq. NaHCO3 solution. The org. extract is dried over MgSO4, filtered and evaporated. The crude product is purified by chromatography on prep. TLC plates with EA-heptane to give (RS)-2,3-diethyl-5-[3-(3-ethyl-5-methyl-4-oxiranylmethoxy-phenyl)-[1,2,4]oxadiazol-5-yl]-pyridine (92 mg) as an oil.
