実験手順

A solution of 0.73 g of 1,1'-(azodicarbonyl)dipiperazine in 10 ml of toluene was added dropwise at room temperature to a suspension of 0.60 g of 2-(3-quinolylmethyleneaminooxy) ethanol (prepared as described in Preparation 3), 1.10 g of 5-(4-hydroxy-benzyl)-3-tritylthiazolidine-2,4-dione and 0.72 ml of tributylphosphine in 30 ml of tetrahydrofuran, and the resulting mixture was stirred for 16 hours. At the end of this time, the reaction product was purified by column chromatography through silica gel, using a 1:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 1.45 g of the title compound as a crystalline powder, melting at 127°-130° C.
