To a solution of 4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)benzoic acid (302 mg, 1.0 mmol) in anhydrous N,N-dimethylformamide (10 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (570 mg) at 0° C. A solution of N-(7-(5-amino-2-methylpyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide (318 mg, 1.0 mmol) in anhydrous N,N-dimethylformamide (5 mL) was mixed with N,N-diisopropylethylamine (387 mg, 3.0 mmol) and immediately added to the reaction at 0° C. It was stirred at 0° C. for 10 minutes and then at room temperature for 4-5 hours. The reaction was diluted with ethyl acetate (15 mL) and water (10 mL) and the aqueous layer was extracted with ethyl acetate (3×15 mL). The combined organic layers were dried, concentrated, and purified by prep-HPLC to give the product (6.4 mg, 1.1%). LCMS (ESI): RT (min)=0.760, M+H+=603.4, method=A; 1H NMR: (MeOH-d4, 400 MHz): δ 9.40 (d, J=2.0 Hz, 1H), 9.18 (s, 1H), 8.59 (d, J=2.0 Hz, 1H), 8.51 (s, 1H), 8.37 (s, 1H), 8.29 (d, J=4.4 Hz, 1H), 8.19 (s, 1H), 8.07-01 (m, 2H), 7.83 (d, J=1.6 Hz, 1H), 3.88 (s, 2H), 3.51 (d, J=12.4 Hz, 2H), 3.31 (t, J=1.6 Hz, 2H), 3.22 (t, J=1.6 Hz, 2H), 3.06 (d, J=12.4 Hz, 2H), 2.92 (s, 3H), 2.72 (s, 3H), 2.51 (t, J=1.6 Hz, 2H), 2.02-1.97 (m, 1H), 1.05-1.04 (m, 2H), 0.95-093 (m, 2H).
