実験手順

A suspension of sodium hydride (4.0 g, 100 mmole) in dry tetrahydrofuran (350 mL) under a nitrogen atmosphere was cooled in an ice bath. Pentyl mercaptan (10.8 g, 100 mmole) was added dropwise over 10 minutes. The resulting suspension of sodium alkylmercaptide was added in portions over 30 minutes to a stirred solution of 1-chloro-3-iodopropane (20.44 g, 100 mmole) in tetrahydrofuran (450 mL) that had been cooled to -78° C. The mixture was allowed to warm to ambient temperature overnight, then washed with brine, dried over MgSO4, and concentrated under vacuum. The resultant oil was distilled under water aspirator pressure to yield the desired product (10.67 g, 59% yield), b.p. 113°-119° C. (20 mm Hg).
