Versuchsvorschrift

The mixture of (1-chloro-isoquinolin-3-yl)-(5-methyl-1H-pyrazol-3-yl)-amine (100 mg), phenylboronic acid (84 mg), Na2CO3 (145 mg), Tetrakis(triphenyl-phosphine)palladium(0) (40 mg), N,N-dimethylformamide (DMF) (1 ml) and water (1 ml) was heated at 180° C. for 30 minutes under microwave irradiation. After reaction finished, the reaction mixture was purified by preparative LC-MS to give (5-methyl-1H-pyrazol-3-yl)-(1-phenyl-isoquinolin-3-yl)-amine (40 mg). LC-MS m/e 301(MH+).+.) 1H NMR(CDCl3): δ 2.23(s, 3H), δ 5.86(s, 1H), δ 7.22(m, 1H), δ 7.40(m, 1H), δ 7.55(m, 5H), δ 7.70(m,4H), δ 7.90(d, 1H).
