Procedure
In a similar fashion using route 39 general procedure 95, 2-fluoro-4-methyl-1-nitrobenzene (2 g, 12.9 mmol) in EtOH (24 ml) and Na2SO3 (2.04 g, 16.0 mmol) in EtOH:water (40 ml: 32 ml) at 70° C. for 14 h gave the title compound (7 g) which was used in the next step without further purification.
