Reaction Conditions

Reaction Steps

At 25° C., 16.7 g (0.1 mol) of 2-[(methylsulfanyl)methyl]butyryl chloride were added to a solution of 12.7 g (0.1 mol) of n-propyl cyanoacetate in CH2Cl2, and the mixture was cooled to 0° C. At 0° C., 20.2 g (0.2 mol) of triethylamine were then added dropwise. After 16 h of stirring at 25° C., the reaction mixture was hydrolyzed and the organic phase was separated off, dried and concentrated. Customary purification gave 15 g (58% of theory) of the title compound as a yellow liquid (b.p. 118 to 120° C./2 mbar).
