Diisopropylethylamine → 7-Chloro-3-{1-[6-(2,3-dihydroindole-1-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one

Participants

Reaction Steps

110 mg (0.36 mmol) 7-chloro-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one were added to 87.6 mg (0.34 mmol) (6-chloropyrimidin-4-yl)-(2,3-dihydro-indol-1-yl)-methanone and 63 μL (0.37 mmol) DIPEA in 2.5 mL DMF. The reaction mixture was stirred overnight at RT, then concentrated by rotary evaporation using the rotary evaporator and purified by preparative HPLC. The corresponding product fractions were combined and evaporated down using the rotary evaporator. The residue was taken up in DMF and combined with methanol. The substance was precipitated, suction filtered, washed with a little methanol and dried.
