After stirring for 1 h at room temperature the solvent was removed in vacuo and the residue acidified with 2M HCl, before extraction into ethyl acetate (2×50 mL). The organic solution was dried (MgSO4) and the solvents removed in vacuo to afford the title compound as a bright yellow solid (115 mg).
