Reaktionsschritte
A solution of 1-ethyl-3-methyl-1H-pyrazol-4-ylamine (1.345 g, 10.75 mmol, commercially available) and (6-trifluoromethyl-pyridin-3-yl)-acetonitrile (distilled 166-175° C./2 mb, 1.0 g, 5.4 mmol) in MeOH (10 mL) was treated with HCO2NH4 (1.694 g, 26.86 mmol) and 10% Pd/C (200 mg) and stirred at 80° for 1.5 h. Filtration, concentration and purification by HPLC afforded the title compound (0.213 g, 13%) as a light brown oil. MS m/e: 299.3 [M+H]+.
