Yield:312904-91-9 79%

Reaction Conditions:

in N,N-dimethyl-formamide at 20; for 2 h;

Steps:

96A.1

5 g (40.9 mmol) of 3-fluoropyridine-2-carbonitrile were dissolved in 40 ml of N,N-dimethylformamide. 3.2 g (45 mmol) of sodium thiomethoxide were then added slowly at room temperature. The mixture was stirred at room temperature for 2 h and then poured onto 500 ml of water. This resulted in the precipitation of a solid which was filtered off and washed with water. Drying under high vacuum gave 5.1 g (79% of theory) of the intermediate 3-(methylsulphanyl)pyridine-2-carbonitrile.
