実験手順

Compound 12 (0.1 g, 0.4 mmol, 1 eq), 4-methylthiazol-2-amine (60 mg, 0.53 mmol, 1.2 eq), 2-(1H-7-Azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (348 mg, 0.915 mmol, 2.10 eq), and DIEA (160 μL, 0.915 mmol, 2.10 eq) were dissolved in CH2Cl2 (5 mL) and DMF (1 mL) and stirred rt for 48 h. The reaction was diluted with CH2Cl2 and washed with water (1×). The organics were dried (MgSO4), filtered and concentrated in vacuo. Purification by flash chromatography on silica gel afforded 35 mg (25%) of the title compound as a white solid: 1H NMR (400 MHz, CDCl3) δ 8.60 (d, J=2.3 Hz, 1H), 8.56 (dd, J=4.7, 1.1 Hz, 1H), 8.33 (d, J=4.8 Hz, 1H), 7.83 (ddd, J=8.2, 2.4, 1.5 Hz, 1H), 7.55 (dd, J=8.1, 4.7 Hz, 1H), 7.31 (s, 1H), 6.94-6.89 (m, 1H), 8.86 (s, 1H), 3.40 (s, 3H), 2.28 (s, 3H); [M+1]+: 326.2.
