実験手順

5-(2,4-bis-benzyloxy-5-bromo-phenyl)-isoxazole-3-carboxylic acid ethyl ester was suspended in ethanol and ethylamine (2M in methanol, 3 eq), the resulting yellow suspension was heated to reflux (80° C.) under nitrogen, at which point the reagents went into solution. This was heated for 14 hours, then left to cool to ambient temperature. A white precipitate formed, which was filtered off and washed with further ethanol before being dried in vacuo.
