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

Participants

Reaction Steps

227 mg (0.78 mmol) 1-piperidin-4-yl-1,3-dihydro-imidazo[4,5-b]pyridin-2-one dihydrochloride were added to 200 mg (0.74 mmol) (6-chloropyrimidin-4-yl)-(3-methyl-indol-1-yl)-methanone and 413 μL (2.40 mmol) DIPEA in 5 mL DMF. The reaction mixture was stirred overnight at RT and then purified by preparative HPLC. The product fractions were combined and concentrated by rotary evaporation using the rotary evaporator. The residue was taken up in methanol and purified through a silica gel column. The product fractions were combined and concentrated by rotary evaporation using the rotary evaporator.
