Versuchsvorschrift

7.0 g (25 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one and 2.5 g (12 mmol) 4-bromopicolinic acid in 25 mL NMP were stirred for 2 h at 110° C. The reaction mixture was combined with some formic acid and purified by preparative HPLC-MS. The product-containing fractions were combined and evaporated down. The residue was stirred with MeOH, suction filtered and dried.
