실험 절차

A solution of 2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.1 g, 0.499 mmol), 8-bromoisoquinoline (0.155 g, 0.748 mmol), potassium phosphate (0.317 g, 1.495 mmol), CuI (9 mg, 0.047 mmol) and L-Proline (11 mg, 0.095 mmol) in dry DMF (3 mL) was heated at 150° C. for 16 h. The reaction mixture was diluted with water and extracted with EtOAc. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain crude, which was purified by reverse phase HPLC to yield 5-(isoquinolin-8-yl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (TFA salt, CD3OD) d (ppm): 8.8 (d, 1H), 8.62 (d, 1H), 8.42 (bs, 1H), 8.4 (d, 1H), 8.3 (t, 1H), 8.0 (d, 1H), 7.42 (s, 1H), 7.0 (d, 1H), 6.87 (bs, 1H), 4.7 (d, 1H), 4.3 (d, 1H), 3.8 (m, 1H), 3.6 (m, 1H), 3.16 (m, 4H), 2.8 (m, 1H), 2.4 (s, 3H).
