実験手順

To a solution of 2-cyano-3,3-bis-methylsulfanyl-acrylamide 12 (100 mg, 0.574 mmol) in ethanol (5 ml) was added N-cyclopropyl-3-hydrazino-4-methyl-benzamide trifluoroacetic acid salt (0.183 g, 0.574 mmol) and diisopropylethylamine (0.100 ml, 0.574 mmol). The mixture was heated to 65° C. for 18 h. The mixture was cooled to room temperature. Solvents were removed in vacuo. EtOAc was added to the residue and a solid precipitated. The solid was collected on a fritted funnel and was washed with EtOAc and ether to give the desired 5-amino-1-(5-cyclopropylcarbamoyl-2-methyl-phenyl)-3-methylsulfanyl-1H-pyrazole-4-carboxylic acid amide 13. HPLC (4 minute 10-90 gradient) tR 1.98 min; MS m/z 439.08 [M+H]+; 1H NMR (DMSO-d6, 500 MHz) δ 8.47 (d, J=3.7, 1 H), 7.90 (d, J=7.9, 1 H), 7.78 (s, 1 H), 7.49 (d, J=8.0, 1 H), 6.81 (bs, 2 H), 6.30 (s, 2 H), 2.86 (m, 1 H), 2.45 (s, 3 H), 2.11 (s, 3 H), 0.68 (m, 2 H), 0.57 (m, 2 H) ppm.
