実験手順
3-(2-{2-[2-(2-tert-butoxycarbonylamino-ethoxy)-ethoxy]-ethoxy}-ethoxy)-propionic acid (690 mg 1.9 mmol), EDAC (403 mg 2.1 mmol), HOBT (284 mg 2.1 mmol), NMM (420 uL 3.8 mmol) and 5-(4-chloro-3-methanesulfonyl-phenyl)-4-methyl-thiazol-2-ylamine (520 mg 1.7 mmol) were combined in dimethylformamide (16 ml) and stirred over night at room temperature. The solvent was removed under reduced pressure and the residue dissolved in dichloromethane (150 ml), washed with 1M HCl aqueous solution (50 ml) and saturated aqueous sodium hydrogen carbonate (50 ml), dried (Magnesium sulphate), filtered and evaporated. The residue was purified by flash chromatography using 50 g IST silica flash cartridge eluting with 0-2% methanol/dichloromethane to yield (2-{2-[2-(2-{2[5-(4-chloro-3-methanesulfonyl-phenyl)-4-methyl-thiazol-2-ylcarbamoyl]-ethoxy}-ethoxy)-ethoxy]-ethoxy}-ethyl)-carbamic acid tert-butyl ester as an oil (1.1 g residual solvent present) 1H NMR (400 MHz CDCl3) 10.3 (br s, 1H), 8.2 (s, 1H), 7.6 (m, 2H), 7.2 (br s, 1H), 3.9 (t, 2H) 3.8-3.5 (br m, 14H), 3.3 (br m, 5H), 2.8 (t, 2H), 2.4 (s, 3H), 1.4 (s, 9H).
