Reaction Steps

Triphenylphosphine (2.01 g) in dry dichloromethane (16 ml) was added dropwise over 20 min to a stirred solution of 3-[2-(3-phenoxypropoxy)ethoxy]-1-propanol (1.5 g), and carbon tetrabromide (2.54 g) in dry dichloromethane (27 ml) at 0° C. under nitrogen. The solution was allowed to warm to room temperature and stirred under nitrogen for 4 h. The solution was purified by FCC eluting with System F (4:1) to give the title compound (1.75 g) as a colourless oil. T.l.c. (System F 1:1) Rf 0.55
