Procedure

A solution of butyl lithium (1.6M in hexane, 1.03 ml) was added to a stirred solution of the product from step (i) (0.5 g) in diethylether (20 ml) at −78° C. After 1 h, 4-ethylsulfanyl-benzaldehyde (0.25 g) was added and stirred for a further 1 h. The reaction was quenched with water, extracted with diethylether and the organic layer dried, then evaporated under reduced pressure. The residue was purified by chromatography on silica eluting with 50% diethylether/isohexane. Yield 0.7 g
