Participants

Reaction Steps

A solution of 2-[2-(4-bromo-phenyl)-4-isopropyl-oxazol-5-yl]-propan-1-ol (225 mg, 0.694 mmol) and 3-(4-hydroxy-2-methyl-phenyl)-propionic acid methyl ester (190 mg, 0.972 mmol) in toluene (15 mL) is degassed and filled with nitrogen for 3 times. Tributylphosphine (224 mg, 1.11 mmol) is added to the reaction mixture under nitrogen at 0° C., followed by addition of of 1,1′-(azodicarbonyl)-dipiperidine (280 mg, 1.11 mmol). The reaction mixture is allowed to warm to room temperature and stirred overnight, the mixture is loaded directly on silica gel column chromatography with 10–15% EtOAc/Hexanes to afford the title compound (320 mg, 92%).
