Product 1

HCID 221709074-(5-Chlorothiophen-2-yl)-2-cyclopropylmethylthiobenzonitrileYield 91%

Procedure

0.9 g (4.0 mmol) of 4-(5-chlorothiophen-2-yl)-2-fluorobenzonitrile and 0.9 g (4.3 mmol) of S-cyclopropylmethylisothiourea hydrobromide were allowed to react in the same manner as described above in Example 8 (4), and purification of the crude product by silica gel column chromatography afforded 1.1 g of 4-(5-chlorothiophen-2-yl)-2-cyclopropylmethylthiobenzonitrile (yield 91%) as yellow feathery crystals (m.p. 123-124° C.).
