Procedure
13.1 g of triphenyphosphine are added to a solution of 8.2 g of 3-picolyl chloride hydrochloride in 120 ml of dimethylformamide. After stirring for 5 minutes, the mixture is heated at reflux for 30 minutes in a microwave apparatus and then cooled to 5° C. The crystals obtained are filtered off, rinsed with dimethylformamide and then with ether, and dried under reduced pressure, allowing the expected product to be isolated.
