Diisopropylethylamine → (S)-tert-butyl 2-((4-(4-(4-(5-benzoylpyrimidin-2-yl)piperazin-1-yl)-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate

Participants

Reaction Steps

To a mixture of phenyl(2-(piperazin-1-yl)pyrimidin-5-yl)methanone HCl salt (141.6 mg, 0.38 mmol) and (S)-tert-butyl 2-((4-(4-chloro-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate (150 mg, 0.38 mmol) in dioxane (10 mL) was added diisopropylethylamine (1 mL), and the reaction was stirred at room temperature overnight. LCMS showed the reaction was completed. The solvents were removed under reduced pressure, and the residue was purified by silica gel chromatography (petroleum ether:ethyl acetate=1:1) to give (S)-tert-butyl 2-((4-(4-(4-(5-benzoylpyrimidin-2-yl)piperazin-1-yl)-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate (230 mg, 95%) as a yellowish solid. (MS (ES+) C31H37N11O4 requires: 627, found: 573 [M-56+H]+.
