3-Fluoro-4-formylbenzonitrile (2.00 g, 13.4 mmol; Example 8A) was dissolved in DMSO (27 ml), and sodium methanethiolate (1.50 g, 21.5 mmol) was added with ice-bath cooling. The mixture was stirred for 45 min and then diluted with water (100 ml). The resulting precipitated product was filtered off with suction, washed with water and dried under reduced pressure. This gave 1.36 g (51% of theory) of the target compound as a yellow crystalline solid.
