Procedure

A stirred solution of 1,2,3,5-tetrahydrobenzo[e]pyrrolo[2,1-c]-1,2,4-thiadiazine-5,5-dioxide (222 mg; 1 mmol) in H2SO4 (2 ml) at 5° C. was added a solution of KNO3 (122 mg; 1.2 mmol) in H2SO4 (2 ml). The reaction mixture was allowed to warm up to rt. and stirred for 2 h. The reaction mixture was poured into ice water, filtered and air dried to give 190 mg (71%) product.
