Procedure

To a solution prepared by adding 90 g of 2,4-dimethoxybenzenesulfonic acid obtained in Step (1) above to 200 ml of chloroform, was added 225 ml of nitric acid (d=1.42) with stirring. The reaction mixture was stirred at 25° to 30° C. for 2 hours and 300 ml of acetonitrile was added thereto. The crystals thus-precipitated were collected by filtration and washed with 100 ml of acetonitrile.
