Versuchsvorschrift

The product from step (ii) (8.6 g) was added to phosphorous oxychloride (50 ml) and the resulting suspension stirred at 100° C. for 15 h. The reaction mixture was allowed to cool and the phosphorous oxychloride evaporated under reduced pressure. The residue was diluted with water (100 mL) and the suspension adjusted to pH 7 with NaHCO3. The mixture was heated at 50° C. for 1 h and allowed to cool. The solid was collected by filtration, washed with water, EtOAc and dried under vacuum to give the subtitle compound 9.05 g.
