Procedure

The product from Step C (8.3 g) was dissolved in dimethylformamide (40 ml) and was treated with N-chlorosuccinimide (4.4 g). The mixture was heated and at 65° C. a color change from yellow to red occurred. Heating was discontinued and the reaction was allowed to stir at room temperature overnight. The reaction mixture was diluted with water and ice and the solid was filtered and washed with water. After air drying the solid was taken up in ethyl acetate and dried further with magnesium sulfate. The ethyl acetate was removed by evaporation at reduced pressure to afford the product as a slightly pink solid (9.2 g), m.p.=177°-178° C. NMR (DMSO-D6): δ10.2 (OH), 7.3 (1H), 6.9 (1H), 3.9 (2H), 2.6 (2H), 1.9 (2H), 1.7 (2H).
