Participants

Reaction Steps

A fully reacted mixture of equimolar amounts of diethyl azodicarboxylate and triphenylphosphine in THF is admixed with equimolar amounts of 4-(5-undecylpyrimidin-2-yl)phenol and 3-ethyl-1-cyclopenten-1-yl-methanol (prepared by LiAlH4 reduction of methyl 3-ethyl-1-cyclopentene-1-carboxylate as described by Takeda, Bull.Chem.Soc.Jpn. 50 (7), 1831 (1977)). The mixture is stirred for 24 h at room temperature and then evaporated to dryness under reduced pressure. Purification by chromatography (silica gel, dichloromethane) and recrystallization affords the target compound.
