To a solution of 5-(cyclopropylethynyl)-2-(piperazin-1-yl)pyrimidine HCl salt (172 mg, 0.44 mmol) and (s)-tert-butyl 2-((4-(4-chloro-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate was added diisopropylethylamine (169 mg, 1.311 mmol), and the reaction mixture was stirred at room temperature. LCMS showed the reaction was completed. The mixture was concentrated, and the residue was purified by silica gel chromatography, eluting with petroleum ether:ethyl acetate=1:2, to afford (S)-tert-butyl 2-((4-(4-(4-(5-(cyclopropylethynyl)pyrimidin-2-yl)piperazin-1-yl)-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate (240 mg, 94%) as a yellowish solid. MS (ES+): C29H37N11O3 requires: 587, found: 588 [M+H]+.
