实验步骤: 4-amino-2,5-difluoro-benzoic acid (Rare Chemicals GmbH; 700 mg, 4.04 mmol), [1-(pyrrolidin-1-ylmethyl)cyclopropyl]methanamine (Intermediate 33; 655 mg, 4.25 mmol), HATU (1.69 g, 4.44 mmol) and DIPEA (2.1 mL, 12.12 mmol) were combined in DMF (10 mL) and stirred at room temperature for 2 hours. The reaction mixture divided into two portions and each loaded on to an SCX-2 column (20 g) pre-wet with MeOH (2 column volumes), flushed with MeOH (2 column volumes) and eluted with 2M ammonia in MeOH. Product containing fractions were evaporated and the residue taken up in DCM and purified on a silica column eluting with a 0-5% gradient of 2M ammonia in MeOH/DCM then 5% 2M ammonia in MeOH/DCM. Fractions containing product were combined and evaporated to yield the title compound as an orange gum which solidified on standing to an orange solid (472 mg, 38%) flushed with MeOH (2 column volumes) eluted with 2M ammonia in MeOH Product containing fractions were evaporated purified on a silica column eluting with a 0-5% gradient of 2M ammonia in MeOH/DCM Fractions containing product evaporated

实验步骤: 4-amino-2-fluoro-5-methoxy-benzoic acid (Intermediate 183; 500 mg, 2.70 mmol), [1-(pyrrolidin-1-ylmethyl)cyclopropyl]methanamine (Intermediate 33; 417 mg, 2.70 mmol), HATU (1.545 g, 4.05 mmol) and DIPEA (1.415 mL, 8.10 mmol) were dissolved in DMF (8 mL) and left to stir for 3 hours at room temperature. The reaction mixture was loaded onto an SCX-3 column pre-washed with methanol. The column was washed with methanol eluted with 2% 7N ammonia/methanol. Product containing fractions were combined and evaporated and the residue purified on a silica column (5-12% MeOH ammonia/DCM gradient elution) to yield the title compound as an orange-brown solid (200 mg, 23%). left pre-washed with methanol The column was washed with methanol eluted with 2% 7N ammonia/methanol Product containing fractions evaporated the residue purified on a silica column (5-12% MeOH ammonia/DCM gradient elution)

实验步骤: 4-(4-(1-(4-(2-ethoxy-2-oxoethoxy)phenyl)cyclopropylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoic acid (330 mg, 0.603 mmol), (1-(pyrrolidin-1-ylmethyl)cyclopropyl)methanamine (112 mg, 0.723 mmol), HATU (344 mg, 0.904 mmol), and Hunig's Base (0.526 mL, 3.01 mmol) were stirred in DCM (Volume: 5 mL) for 16 h. The solvent was removed and the crude material was purified by silica gel chromatography using EtOAc then 5% DCM/MeOH to give ethyl 2-(4-(1-(4-(4-((1-(pyrrolidin-1-ylmethyl)cyclopropyl)methylcarbamoyl)phenylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)cyclopropyl)phenoxy)acetate (268 mg).
