실험 절차
Thiosalicylic acid was added to a solution of the product from Example 1 part (iv) (474 mg) in trifluoroacetic acid (10 ml) was added thiosalicylic acid (351 mg) and the resulting suspension was heated to 60° C. for 4 hours. The mixture was concentrated in vacuo and the residue dissolved in EtOAc and washed with NaHCO3 (aq), brine, dried (MgSO4) and evaporated to give crude material. Purification by column chromatography (50% EtOAc/hexane as eluent) gave the sub-title compound (0.13 g).
