Reaction Steps

440 mg (1.60 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one and 121 mg (0.40 mmol) 6-(3,5-difluoro-benzoyl)-3,4-dimethyl-3H-benzoxazol-2-one were combined and heated to 300° C. for approx. 10 min using the hot gun. Then the mixture was dissolved in DMF and purified by preparative HPLC-MS. The fractions containing the product were combined and the organic solvent was evaporated down. The residue was neutralised with 1N aqueous sodium hydroxide solution, the precipitate formed was suction filtered, washed with water and dried i. vac.
