Ethylamine in MeOH solution (2 M, 80 mmol, 40 ml) was added to a suspension of ethyl 5-(2,4-bis(benzyloxy)-5-chlorophenyl)isoxazole-3-carboxylate (9.51 mmol) in EtOH (50 ml) and the reaction mixture was heated to 80° C. with stirring for 18 h, affording a yellow homogeneous solution, which was allowed to cool to RT. A flocculent colourless solid formed upon cooling to 4° C. After filtration, washing with cold EtOH and drying under vacuo, the desired compound was obtained.
