반응 단계
In a similar fashion using route 39 general procedure 95, 1,4-difluoro-2-methyl-5-nitrobenzene (1.2 g, 6.93 mmol) in EtOH (10 ml) and Na2SO3 (1.98 g, 15.7 mmol) in EtOH:water (40 ml:25 ml) at 70° C. for 16 h gave the title compound (1.2 g, 73%) which was used in the next step without purification.
