実験手順
A procedure similar to that described in Preparation 4 was repeated, except that 1.94 g of 2-hydroxymethyl-1-methyl-1H-imidazo[4,5-c]pyridine (prepared as described in Preparation 73), 5.71 g of 5-(4-hydroxybenzyl)-3-triphenylmethylthiazolidine-2,4-dione, 3.1 ml of tributylphosphine, 3.09 g of 1,1'-(azodicarbonyl)dipiperidine and 50 ml of toluene were used, to give the title compound as a crude product. This crude product was purified by column chromatography through silica gel, using a gradient elution method, with mixtures of ethyl acetate and methanol in ratios ranging from 1:0 to 10:1 by volume as the eluent, to give 3.55 g of the title compound having Rf=0.08 (on silica gel thin layer chromatography using ethyl acetate as the developing solvent).
