Diethyl Ether → HCID 15086709, compound

Participants

Reaction Steps

To a solution of 3-methyl-5-acetoxy-isoxazole (14 g, 112 mM) in diethyl ether (400 mL) at 0° C., was added a 3M solution of phenylmagnesium bromide in diethyl ether (44.7 mL, 134 mM) dropwise. After the addition was complete, the reaction mixture was stirred for 30 minutes. When pH 7 buffer (100 mL) was added, the layers were separated. The aqueous layer was extracted with diethyl ether (2×75 mL). The combined ethereal extracts were washed with saturated aqueous sodium chloride (50 mL), dried over MgSO4, filtered and concentrated under reduced pressure to give 3-methyl-5-(1-hydroxy-1-phenylethyl)-isoxazole as an amber oil (20.2 g, 89%) that was used without further purification.
