Reaction Steps

To a solution of 6-(3-(aminomethyl)phenyl)-4-(((1R)-2-fluoro-1,2-dimethylpropyl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide (Example 68, 15 mg, 0.041 mmol), cyclopropanecarboxylic acid (3.40 μl, 0.041 mmol) and triethylamine (8.49 μl, 0.061 mmol) in DMF (0.5 mL) was added BOP (17.96 mg, 0.041 mmol) and the resulting mixture was stirred at rt for 30 minutes. The reaction mixture was purified by reverse-phase preparative HPLC (condition C) to yield the title compound (9.6 mg, 53%). HPLC (condition J): retention time=2.140 minute. LC/MS (M+H)+=438.2. 1H NMR (500 MHz, MeOD) δ ppm 8.08 (1 H, s), 7.86 (1 H, d, J=1.7 Hz), 7.50-7.57 (2 H, m), 7.35 (1 H, t, J=7.6 Hz), 7.19 (1 H, d, J=7.5 Hz), 7.09 (1 H, d, J=1.7 Hz), 4.39-4.49 (3 H, m), 1.54-1.61 (1 H, m), 1.51 (3 H, d, J=3.6 Hz), 1.44-1.48 (6 H, m), 0.89-0.95 (2 H, m), 0.72-0.78 (2 H, m).
