98% | With N-ethyl-N,N-diisopropylamine; HATU; In dichloromethane; at 20℃; for 1h; | j00721j A solution of 3-(6-((4-(trifluoromethoxy)phenyl)amino)pyrimidin-4-yl)benzoicacid (884 mg, 2.35 mmol) in DCM (10 mL) was charged with HATU (1.3 g, 3.48 mmol),DIPEA (0.8 mL, 4.70 mmol) and tert-butyl (20-amino-3 ,6,9, 12,15,1 8-hexaoxaicosyl)carbamate (1 g, 2.35 mmol) and stirred at room temperature for 1 h. The reaction mixture was dilutedwith DCM (60 mL), washed with water (30 mL) and dried over anhydrous Na2SO4, filtered and concentrated in vacuo resulting in a crude compound which was purified by chromatographyon silica gel, eluting with 2-4% methanol in DCMto give 1.80 g, 98% yield of the titlecompound as a colorless oil. ?H NMR (400 MHz, DMSO-d6): oe = 9.96 (s, 1H), 8.67 - 8.80 (m,2H), 8.54 (t, J= 1.8 Hz, 1H), 8.20 (d, J= 7.9 Hz, 1H), 7.99 (d, J= 7.7 Hz, 1H), 7.81 -7.89 (m,2H), 7.63 (t, J= 7.7 Hz, 1H), 7.31 - 7.40 (m, 3H), 6.76 (t, J= 5.6 Hz, 1H), 3.42 - 3.60 (m,24H), 3.36 - 3.40 (m, 2H), 3.04 (q, J= 6.0 Hz, 2 H), 1.37 (s, 9H). |
j00273j A solution of 3-(6-((4-(trifluoromethoxy)phenyl)amino)pyrimidin-4-yl)benzoicacid (329 mg, 0.877 mmol) in DCM (5 mL) was charged with HATU (400 mg, 1.05 mmol) andtert-butyl (20-amino-3 ,6,9, 12,15,1 8-hexaoxaicosyl)carbamate (409 mg, 0.965 mmol) and stirred at room temperature for 10 mm. This solution was charged with DIPEA (226 mg, 1.75 mmol) and stirred at room temperature for 5 h. The reaction mixture was diluted with water (10 mL) and extracted with DCM (3 X 15 mL). The combined organic layers were dried overanhydrous Na2504, filtered and concentrated in vacuo resulting in a crude compound 600 mg as colorless liquid. The crude compound was used in the next step without further purification. MS (ES): m/z = 782.30, 783.30 [M+H] LCMS: tR = 3.32 mm. |
