Reaktionsschritte

To a stirred solution of Example L (1.2 g, 3.5 mmol) in THF (6 ml) was added borane-methylsulfide (9 mmol). The mixture was heated to reflux for 90 min and cooled to RT, and 6 N HCl was added and heated to reflux for 10 min. The mixture was basified by adding sodium hydroxide, followed by extraction with ethyl acetate. The organic layer was dried (Na2SO4) filtered and concentrated in vacuo to yield 3-tert-butyl-1-[3-(2-morpholinoethyl)phenyl]-1H-pyrazol-5-amine (0.78 g), which was used without further purification.
