Procedure

[2-(5-Phenyl-thiazol-2-ylamino)-pyridin-4-yl]-methanol 8-7 (0.500 g, 1.77 mmol) was stirred in anh CH2Cl2 (5 mL) under N2. N,N-Dimethylformamide (0.137 mL, 1.76 mmol, 1 equiv) was added followed by the addition of phosphorous oxychloride (0.165 mL, 1.76 mmol). After 1.5 h the reaction was concentrated and quenched by the addition of saturated NaHCO3 (aq). A precipitate formed which was filtered and washed with water to provide the titled compound. 1H NMR (DMSO-d6) δ11.49 (bs, 1H), 8.34 (d, 1H, J=5.2 Hz), 7.81 (s, 1H), 7.60 (d, 2H, J=7.7 Hz), 7.39 (t, 2H, J=7.6 Hz), 7.26 (t, 1H, 7.0 Hz), 7.13 (s, 1H), 6.99 (d, 1H, J=5.3 Hz), 4.77 (s, 2H).
