To a solution of (S)-tert-butyl 2-((4-(4-(4-(5-bromopyrimidin-2-yl)piperazin-1-yl)-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate (100 mg, 0.17 mmol) and Pd(Amphos)Cl2 (11.7 mg, 0.17 mmol) in THF (2 mL, dried) was dropwise added a solution of (1-phenylethyl)zinc(II) bromide in THF (7.0 mL, 0.5 M, 3.4 mmol). The reaction mixture was stirred at 70° C. for 1 hour under N2, then cooled to room temperature and diluted with ethyl acetate (50 mL). After filtration, the filtrate was concentrated to afford (2S)-tert-butyl 2-((4-(4-(4-(5-(1-phenylethyl)pyrimidin-2-yl)piperazin-1-yl)-1,3,5-triazin-2-ylamino)-1H-pyrazol-1-yl)methyl)morpholine-4-carboxylate as a white solid (130 mg, crude), which was directly used in the next step without further purification. MS (ES+) C32H41N11O3 requires: 627, found: 628 [M+H]+.
