Reaction Steps

23.8 g (0.313 mol) of 1-propanethiol were added in the course of 30 minutes to a mixture of 7.9 g (0.313 mol) of 95% pure sodium hydride in 200 ml of THF while flushing with nitrogen and stirring, a temperature of 25-30° C. being maintained by means of cooling. After the mixture had been stirred for 1 hour, 54 g (0.25 mol) of 2,3-dichloro-5-trifluoromethylpyridine in 50 ml THF were added at 25-30° C. in the course of 20 minutes with stirring, and stirring was continued for 10 hours at 23° C. The reaction mixture was concentrated in vacuo, taken up in methylene chloride, extracted with 0.5 N sodium hydroxide solution, dried over magnesium sulfate and concentrated, yielding 63.5 g (99.4%) of the title compound of nD23=1.5120.
