Reaction Steps

A suspension of the product from stage (a) (0.7 g) in polyphosphate ester (7 g) and chlorform (14 ml) was heated at reflux for 5 min. and then poured onto ice. The resulting suspension was stirred with ice for 20 min., then extracted with chloroform (4×20 ml) and the extract dried. Solvent was then removed and the residue purified by column chromatography (G). The title compound was obtained as a reddish semi-solid (0.38 g) which was impure and was employed directly in the next stage.
