Versuchsvorschrift

1-Oxo-7-sulfo 1,2-dihydroisoquinoline-4-carboxylic acid (5 g) was added to chlorosulphonic acid (25 ml). The mixture was heated at 100° C. for 84 h and then slowly dripped onto ice with sting. The mixture was filtered and the residue was washed with water and ether and dried to yield 7-(chlorosulfonyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxylic acid as a buff solid (7.5 g).
