Reaction Steps

0.41 g (1.5 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-benzo[d][1,3]diazepin-2-one and 0.20 g (0.49 mmol) 6-(2,6-dichloro-pyridine-4-carbonyl)-3,4-dimethyl-3H-benzoxazol-2-one were stirred in 3 mL NMP for 3 h at 120° C. The reaction mixture was purified by preparative HPLC. The fractions containing the product were combined and freeze-dried.
