実験手順

At ambient temperature, a solution of 217 mg (1.02 mmol) of 3-(difluoromethyl)-5-fluoro-1-methyl-1H-pyrazole-4-carbonyl chloride in 1 ml of tetrahydrofurane is added dropwise to a solution of 202 mg (0.93 mmol) of N-[1-(indan-2-yl)ethyl]cyclopropanamine and 103 mg (1.02 mmol) of triethylamine in 5 ml of tetrahydrofurane. The reaction mixture is stirred for 1 hr at 70° C. The solvent is removed under vacuum and 100 ml of water are then added to the residue. The watery layer is extracted twice with ethyl acetate (2×150 ml) and the combined organic layers are successively washed by a 1 N solution of HCl, a saturated solution of potassium carbonate and filtered over a chemelut™ cardridge to yield after concentration 190 mg of a beige oil. Column chromatography on silica gel (gradient heptane/ethyl acetate) yields 120 mg (30% yield) of N-cyclopropyl-3-(difluoromethyl)-N-[1-(indan-2-yl)ethyl]-5-fluoro-1-methyl-1H-pyrazole-4-carboxamide as a colourless oil (M+H=378).
