Procedure

275 mg (1.00 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 324 mg (1.00 mmol) 6-(2,6-dichloro-pyrimidine-4-carbonyl)-4-methyl-3H-benzoxazol-2-one and 0.348 mL (2.00 mmol) DIPEA in 5.00 mL DMF were stirred overnight at RT. Then the mixture was purified by preparative HPLC-MS. The fractions containing the product were combined and the organic solvent was evaporated down i. vac. The residue was neutralised with 4N aqueous sodium hydroxide solution and the precipitate formed was suction filtered, washed with water and dried.
