The resulting suspension was warned to 65° C. and hydrazine hydrate (0.1 ml, 87 mg) added carefully. The mixture was stirred at 70° C. for a further 2 hr then cooled and filtered through celite. Solvent was removed in vacuo and the residue purified by chromatography on silica (chloroform/methanol 9:1) to give the title product as a clear oil (25 mg, 26%).
