実験手順

A mixture of 0.120 g (0.26 mmole) of 2-[6-(4-amino-piperidin-1-ylmethyl)-benzoimidazol-1-yl]-4-(3-chloro-phenyl)-thiazole-5-carboxylic acid amide (I.13), 5 mL of dimethylformamide, 0.148 g (0.39 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium, 3-oxide, hexafluorophosphate(1-) (1:1), 0.105 g (0.39 mmole) of triethylamine was stirred for 15 minutes, then 0.056 g (0.39 mmole) of 1-methyl-piperidine-4-carboxylic acid was added. After 3 hours, the mixture was taken up in 100 mL of ethyl acetate, washed twice with 100 mL of water, and then once with 100 mL of brine. The ethyl acetate layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography, eluting with dichloromethane-(methanol-ammonium hydroxide, (92.8:0.3)) (gradient 100:0-0:100) to give 1-methyl-piperidine-4-carboxylic acid (1-{3-[5-carbamoyl-4-(3-chloro-phenyl)-thiazol-2-yl]3H-benzoimidazol-5-ylmethyl}-piperidin-4-yl)-amide (I.14). This material was taken up in 20 mL of dichloromethane, washed with 20 mL of 1M sodium hydroxide solution. The dichloromethane layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give 0.065 g of 1-methyl-piperidine-4-carboxylic acid (1-{3-[5-carbamoyl-4-(3-chloro-phenyl)-thiazol-2-yl]-3H-benzoimidazol-5-ylmethyl}-piperidin-4-yl)-amide (I.14) as a solid.
