The reaction mixture was stirred at -40° C. for half an hour and allowed to warm to ambient temperature. The solvent was removed in vacuo and the residue dissolved in dichloromethane, washed with HO, dried (Na2SO4) and evaporated in vacuo to afford the title compound (0.12 g, 95%) as an orange solid.
