Dimethylformamide → 2-{[6-Chloro-4-(chloromethyl)pyridin-2-yl]amino}-1,3-thiazole-5-carbonitrile

Participants

Reaction Steps

2-{[6-Chloro-4-(hydroxymethyl)pyridin-2-yl]amino}-1,3-thiazole-5-carbonitrile 11-7 (0.132 g, 0.49 mmol) was stirred in anhydrous CH2Cl2 (2 mL) under N2. N,N-Dimethylformamide (0.038 mL, 0.49 mmol) was added followed by the addition of phosphorous oxychloride (0.046 mL, 0.49 mmol). After 2.5 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 afford 2-{[6-chloro-4-(chloromethyl)pyridin-2-yl]amino}-1,3-thiazole-5-carbonitrile as a yellow solid. 1H NMR (DMSO-d6) δ 12.63 (bs, 1H), 8.34 (s, 1H), 7.24 (s, 1H), 7.17 (s, 1H), 4.82 (s, 2H).
