Tributylphosphine → Methyl 4-[3-[4-(4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-oxazolyl]propoxy]phenylacetate

Participants

Reaction Steps

To a mixture of (4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-oxazolepropanol (100 mg), methyl 4-hydroxyphenylacetate (76 mg), tributylphosphine (93 mg) and tetrahydrofuran (5 ml) was added 1,1′-(azodicarbonyl)dipiperidine (116 mg) at room temperature, and the resulting mixture was stirred for 1 hour. After the reaction mixture was concentrated, the residue was subjected to silica gel column chromatography, and methyl 4-[3-[4-(4-chlorophenyl)-2-(2-methyl-1-imidazolyl)-5-oxazolyl]propoxy]phenylacetate was obtained as an oil (103 mg, 70%) from an ethyl acetate-hexane (1:1, v/v)-eluted fraction.
