Tetrafluoro-m-phenylenediamine dihydrochloride → HCID 90052299, compound

Participants

Reaction Steps

To a solution of 4-dimethylaminocrotonic acid hydrochloride (61 mg) in N,N-dimethylformamide (0.5 mL), N-methylmorpholine (135 μL) and isobutyl chloroformate (40 μL) were added under ice cooling, then (S)—N-(5-(2-((3-fluorophenyl)amino)-4-((3-methoxypropyl)amino)pyrimidin-5-yl)-4-pentyn-1-yl)-2-(methylamino)propanamide (J9) dihydrochloride (55 mg) was further added, and the mixture was stirred at the same temperature for 1 hour. To the reaction mixture, saturated aqueous sodium hydrogencarbonate (10 drops) was added, and the solvent was evaporated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography to obtain (S,E)-4-(dimethylamino)-N-(1-((5-(2-((3-fluorophenyl)amino)-4-((3-methoxypropyl)amino)pyrimidin-5-yl)-4-pentyn-1-yl)amino)-1-oxopropan-2-yl)-N-methyl-2-butenamide (10-1, 45 mg).
