실험 절차

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%).
