Versuchsvorschrift
To a solution of [4-([1,3]thiazolo[5,4-b]pyridin-2-yloxy)phenyl]methanol (140 mg, 0.542 mmol) in CH2Cl2 (3.6 mL) was added SOCl2 (43 μL, 0.596 mmol, 1.1 equiv.). The solution was allowed to stir under N2 at rt for 4 h. The reaction mixture was then concentrated to afford the desired product as a cream-colored solid (157 mg, 92%). MS (ESI): mass calcd. for C13H9ClN2OS, 276.0; m/z found, 277.0 [M+H]+. 1H NMR (600 MHz, DMSO-d6): 8.47 (dd, J=4.4, 1.5, 1H), 8.11 (dd, J=8.2, 1.5, 1H), 7.65-7.57 (m, 2H), 7.56-7.47 (m, 3H), 4.85 (s, 2H).
