Procedure

A round-bottomed flask was charged with N-(4-(1-(4-methoxybenzyl)-3-iodo-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorophenyl)-2-(4-fluorophenyl)-3-oxo-2,3-dihydropyridazine-4-carboxamide (100 mg, 0.142 mmol, prepared in Example 63, step A), tert-butyl 3-aminopyrrolidine-1-carboxylate (132 mg, 0.708 mmol), copper(I)iodide (5.39 mg, 0.0283 mmol), (S)-pyrrolidine-2-carboxylic acid (6.52 mg, 0.0566 mmol), K2CO3 (97.8 mg, 0.708 mmol) and DMSO (10 mL). The reaction mixture was stirred at 80° C. overnight. The reaction was cooled to ambient temperature and partitioned between EtOAc and H2O. The phases were separated and the aqueous phase was re-extracted with EtOAc. The combined organic layers were dried (Na2SO4), filtered and concentrated to yield a crude product. The crude product was purified by silica gel chromatography (DCM/7 M NH3 in MeOH from 100/1 to 10/1, v/v) to afford product (61.3 mg, 56.6%). LRMS (APCI pos): m/e 765 (M+1).
