2-Chloroethanol → Phenol, 4-[(2-chloroethyl)thio]-

Participants

Reaction Steps

2-chloro-ethanol (3.9 g, 0.049 mole) was added to a solution of the product of Example 35 (7.4 g, 0.049 mole) in acetone (50 ml). After cooling with an ice bath triethylphosphine (5.6 g, 0.047 mole) was added dropwise over 25 minutes. Ethyl ether (200 ml) and water (75 ml) were added and the layers separated. The organic layer was washed with water (4×50 ml) and saturated sodium chloride (2×25 ml) dried over magnesium sulfate, filtered and concentrated to give a yellow oil. The structure was confirmed by its NMR spectrum.
