반응 단계
To a stirred solution of Example N (2 g, 7.35 mmol) in THF (6 ml) was added borane-methylsulfide (18 mmol). The mixture was heated to reflux for 90 min and cooled to RT, after which 6 N HCl was added and heated to reflux for 10 min. The mixture was basified with NaOH and extracted with EtOAc. The organic layer was dried (Na2SO4) filtered and concentrated in vacuo to yield 3-tert-butyl-1-[3-(2-aminoethyl)phenyl]-1H-pyrazol-5 amine (0.9 g).
