Procedure

To a solution of N-[5-(3,5-difluorobenzyl)-1H-indazol-3-yl]-4-amino-2-[tetrahydro-2H-pyran-4-yl(trifluoroacetyl)amino]benzamide (240 mg, 0.42 mmol) in dichloromethane (20 mL) were added tert-butyl 3-formylazetidine-1-carboxylate (116 mg, 0.63 mmol), trifluoroacetic acid (0.32 mL) and tetramethylammonium triacetoxyborohydride (165 mg g, 0.63 mmol). The mixture was stirred at room temperature overnight, then diluted with dichloromethane, washed with NaHCO3 sat.sol. and brine, dried over sodium sulfate and evaporated to dryness.
