To a solution of triphenylphosphine (1.83 g, 6.98 mmol) in dry tetrahydrofuran (30 ml) at 0° C. and under an atmosphere of nitrogen was added diethyl azodicarboxylate (1.2 g, 6.9 mmol) dropwise. After 20 minutes, lithium iodide and 4-chloro-2-[(3-hydroxy-1-phenylpropyl)amino]-benzonitrile (0.8 g, 2.79 mmol) were added to the mixture and stirring was continued for 5 h. The mixture was then concentrated to dryness, and the residue purified on silica (ether/isohexane 1:4). The title compound was isolated as a colourless solid (0.35 g, 32%).
