Procedure
DDQ (0.25 g) was added to a stirred solution of the product of example 4 (0.25 g) in THF (9 ml) and water (1 ml). The solution was stirred for a further 2 h and the concentrated in vacuo. The residue was purified by flash silica chromatography eluting with ethyl acetate:isohexane (7:3) to give the title compound as a pale pink solid (0.1 g).
