Procedure

To a stirred solution of 8-amino-7-chloro-1,4-benzodioxan-5-carboxylic acid (prepared from the corresponding 7-H acid (prepared as in GB 1571278) by chlorination of the protected form) (1.10 g) in acetonitrile was added biscarbonyldiimidazole (0.77 g). The reaction mixture was stirred at room temperature for 1.5 hours. The solvent was removed under reduced pressure to afford crude 8-amino-7-chloro-1,4-benzodioxan-5-imidazolide.
