Thiophosphoryl chloride → HCID 13545839, compound

Participants

Reaction Steps

A solution of 43.4 mL (0.52 mol) of pyrrolidine in 50 mL of ether was added dropwise to a stirred solution of 116 mL (1.04 mol) of thiophosphoryl chloride in 200 mL of ether at 0° C. (ice bath) under an argon atmosphere. After the addition was completed, the resultant slurry was slowly warmed to room temperature overnight. A trace of pyrrolidinium hydrochloride was removed by filtration and the filtrate was concentrated under vacuum to provide 84.5 g of a clear oil. A portion of this oil (40 g) was distilled at 80° C. (0.25 mm) to provide 18.1 g of the desired dichloride as a clear oil.
