Procedure
In a similar fashion using route 39 general procedure 96, 5-methyl-2-nitro-benzenesulfonic acid 449 (1.8 g, 8.2 mmol), SOCl2 (10 ml) and DMF (0.18 ml) at 90° C. for 3 h gave the title compound (1.2 g) which was used in the next step without further purification. The structure was confirmed by 1H NMR.
