Reaction Steps
0.18 g (0.67 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 0.020 g (0.68 mmol) (2-chloro-pyridin-4-yl)-(4,5-difluoro-2,3-dihydro-indol-1-yl)-methanone and 97 mg (0.70 mmol) potassium carbonate were stirred in 3 mL NMP for 4 h at 130° C., then overnight at RT. The reaction mixture was purified by HPLC. The product-containing fractions were combined and freeze-dried.
