Participants

Reaction Steps

3-Methyl-5-(7-phenyl-furo[3,2-b]pyridin-2-yl)-benzoic acid (79 μmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimidhydrochlorid (86,592 μmol) are dissolved in N,N-dimethylformamid (300.00 μl) and 4-methylmorpholin (157.354 μmol) and 1-hydroxybenzotriazolhydrat (86.849 μmol) are added and stirred 5 min at RT. A solution of 2-amino-2-methyl-propan-1-ol (80,000 μmol) in N,N-dimethylformamid (100.00 μl) is added. The mixture is stirred 4.5 h at RT. The reaction solution is poured into water and extracted with ethylacetate. The combined organic layers are dried over MgSO4 and the solvent is removed in vacuo. The product is isolated after reversed phase column chromatography as yellow solid (33 μmol, 42% yield). HPLC (method A): Rt 2.55 min (purity 98.5%); LCMS (ESI+) (method E): Rt 2.199 min, M+H+401.1 m/z; 1H NMR (500 MHz, DMSO-d6) δ [ppm] 8.60 (d, J=5.1, 1H), 8.18 (s, 1H), 8.16-8.10 (m, 2H), 7.96 (s, 1H), 7.77 (s, 1H), 7.70 (d, J=8.9, 2H), 7.65 (dd, J=14.7, 6.4, 3H), 7.58 (d, J=7.4, 1H), 4.16 (br, 1H), 3.54 (s, 2H), 2.47 (s, 3H), 1.35 (s, 6H).
