Reaktionsschritte

To a suspension of 7-(4-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydroisoquinoline hydrochloride (50 mgs, 0.16 mmol), pyridazine-3-carboxylic acid (30 mgs, 0.24 mmol), HATU (91 mgs, 0.24 mmol), in DMF (1.0 mL) was added NMM (0.05 mL, 0.48 mmol) and the resulting solution was stirred at 23° C. for 16 h. The reaction mixture was then diluted with water/acetonitrile (10:1) and the solid formed was then washed with water, diethylether and dried to give the title compound. MS found for C21H16F3N3O as (M+H)+ 384.1 1H NMR (400 MHz, dmso-d6): mixture of rotomers (˜1.5:1): major rotomer: δ 8.93 (m, 2H), 7.96-7.91 (m, 3H); 7.91-7.55 (m, 6H); 7.32 (m, 1H); 4.90 (s, 2H); 3.44-3.41 (m, 2H); 2.86-2.848 (m, 2H).
