Reaction Steps
53 mg of 32 (207 μmol), 60 mg of 44 (207 μmol), 86 mg of sodium 2-ethylhexanoate (0.52 mmol) in 1 mL of THF are successively introduced into a Wheaton tube, with stirring and under an argon atmosphere. The stirring is maintained at RT for 24 h. The reaction medium is concentrated to dryness. The residues are chromatographed on a silica cartridge (4 g, eluent AcOEt). 45 mg of expected product Ex17 (cream-coloured solid) are recovered.
