Reaction Steps

Phenylethylmercaptan (2.14 ml, 16 mmol) was added to a stirred suspension of 4-cyano-2-fluorobenzaldehyde (2.23 g, 15 mmol) and potassium carbonate (2.21 g, 16 mmol) in dimethylformamide (10 ml) at room temperature under nitrogen atmosphere. The mixture was heated to 75° C. for 1 hour, then cooled and diluted with water (15 ml). A yellow solid precipitated and was filtered, washed with water and then crystallised from cyclohexane (250 ml) to give pale needles of 4-cyano-2-(2-phenylethylthio)benzaldehyde, m.p. 89° C.
