2-(4-Hydroxymethyl-pyridin-2-ylamino)-thiazole-5-carbonitrile (0.883 g, 3.80 mmol) was stirred in anhydrous CH2Cl2 (12 mL) under N2. Dimethylformamide (0.354 mL, 3.80 mmol, 1 equiv) was added followed by the addition of phosphorous oxychloride (0.294 mL, 3.80 mmol). After 4 hours 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.
