Reaction Steps

To 2-(3-hydroxy-propylsulfanyl)-phenol (29.2 g, 158.5 mmol) in THF (450 mL) was added triphenylphosphine (52.0 g, 200.0 mmol). The solution was cooled to −40° C. and diethyl azodicarboxylate (31.5 mL, 164.0 mmol) was added slowly. The solution was warmed to rt and stirred for 2.5 h. The THF was removed by evaporation and the residue was treated with 1 L of Et2O. The formed solids were filtered off, and the filtrate concentrated to an oil which was purified over silica gel (10% Et2O/hexane) to a pink oil (16.2 g, 61%).
