Reaction Steps

A mixture of the product from step (i) (9.5 g) and phosphorous oxychloride (30 ml) was heated at 90° C. for 2 hours. The mixture was evaporated under reduced pressure and poured onto a mixture of ice water and ethyl acetate. The aqueous phase was adjusted to pH 9 with sodium bicarbonate and extracted repeatedly with ethyl acetate. The combined extract was dried (MgSO4) and evaporated. The residue was purified by chromatography eluting with ethyl acetate. Yield 6.1 g. 1H NMR: δ (DMSO) 7.08(br s,2H), 6.40(s,1H), 3.77(s,2H).
