Reaction Steps

3-[2-(3,4,5-Trimethoxy-phenyl)-furo[3,2-b]pyridin-7-yl]-benzylamine (0.036 mmol) is dissolved in acetic acid (1.00 ml) and acetic acid anhydride (0.159 mmol) is added. The reaction solution is stirred 4 d at RT. Water is added and extracted with ethyl acetate. The combined organic layers are washed with brine and dried over MgSO4. The product is isolated after removal of the solvent in vacuo as yellow solid (45% yield). HPLC (method A): Rt 2.52 min (purity 99.4%); LCMS (ESI+) (method E): Rt 1.87 min, M+H+ 433.1 m/z; 1H NMR (500 MHz, DMSO-d6) δ [ppm] 8.57 (d, J=5.1, 1H), 8.44 (t, J=5.7, 1H), 8.09 (d, J=12.1, 1H), 7.97 (d, J=7.8, 1H), 7.76 (d, J=2.8, 1H), 7.69-7.56 (m, 2H), 7.44 (t, J=9.5, 1H), 7.33 (d, J=7.8, 2H), 4.39 (d, J=5.9, 2H), 3.91 (d, J=11.1, 6H), 3.78-3.70 (m, 3H), 1.91-1.77 (m, 3H).
