Reaction Steps

To a mixture of compound 2,4-difluoro-1-nitro-benzene (10 g, 62.9 mmol), pyridine (10 ml, 124 mmol) in MeOH (30 ml) was added the solution of sodium thiomethoxide(20%, 300 mmol) in methanol drop-wise at 0° C. The mixture was stirred for 2 hour and then diluted with dichloromethane. The mixture was washed with brine, dried over MgSO4 and evaporated under reduced pressure. The resulting residue was recrystallized from ethyl acetate to give titled compound (10 g, yield 85%)
