Versuchsvorschrift

To a solution of 200 mg of 8-(cyclohexylmethoxy)-2-methyl-N-[(1R)-2-{methyl[(2-nitrophenyl)sulfonyl]amino}-1-phenylethyl]imidazo[1,2-a]pyridine-3-carboxamide in 3 ml of DMF were added 140 mg of potassium carbonate and 50 mg of 4-methylbenzenethiol, followed by stirring for 3 hours. To the reaction mixture were added water and chloroform/methanol (9/1) to carry out a layer separation operation. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 80 mg of 8-(cyclohexylmethoxy)-2-methyl-N-[(1R)-2-(methylamino)-1-phenylethyl]imidazo[1,2-a]pyridine-3-carboxamide.
