The compound 32-1 (100 mg) prepared according to the same procedure as described in Step 1 was dissolved in ethyl acetate (4 ml) and to the solution were added a solution of 4-chlorobenzylisothiocyanate (123 mg) in ethyl acetate (2 ml), followed by stirring at room temperarure for 18 hours. The obtained reaction mixture was concentrated under reduced pressure and purified by column-chromatography (hexane/ethyl acetate=2/1) to yield the compound 32-2 (201 mg, 99%).
