Diisopropylethylamine → 1-{1-[6-(5-Chloro-2,3-dihydroindole-1-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-1,3-dihydro-imidazo[4,5-b]pyridin-2-one

Participants

Reaction Steps

80 mg (0.27 mmol) 1-piperidin-4-yl-1,3-dihydro-imidazo[4,5-b]pyridin-2-one (dihydrochloride) were added to 100 mg (0.34 mmol) (5-chloro-2,3-dihydroindol-1-yl)-(6-chloropyrimidin-4-yl)-methanone and 100 μL (0.58 mmol) DIPEA in 10 mL DMF. The reaction mixture was stirred for 22 h at RT and then evaporated down i. vac. The residue was combined with 20 mL water and stirred for 30 min at RT. The precipitated product was suction filtered. The purification was carried out using a silica gel column. The product fractions were combined and the solvent was eliminated using the rotary evaporator. The residue was stirred with water, suction filtered and dried.
