PROCEDURE

实验过程

A mixture of the product of step (i) (1.26 g) and Lawesson's reagent (1.56 g) in 1,4-dioxane (30 ml) was heated at reflux for 16 hours. The solvent was evaporated under reduced pressure. The residue was partitioned between ethyl acetate and saturated brine. The organic phase was collected, dried (MgSO4) and solvent evaporated under reduced pressure. Purification was by chromatography eluting with 50% ethyl acetate in toluene.
